# 2-PCA vs 3-PCA

Principal Component Analysis is used to reduce the number of dimensions (features) in a dataset. Say, we have 10 dimensions/features in our dataset. It’s not a smart way to just drop 7–8 features based on an assumption (or a wild guess). One method to tackle this problem could be a feature selection technique (say, Chi-Squared). Feature Selection Techniques help us select the most important ‘k’ features corresponding to the target feature. But again, this will not be an overall representation of all the features (instead, it would be just a few features selected from ‘n’ number of features).
To tackle this problem, we have the Principal Component Analysis (PCA) Dimensionality reduction technique. The principal components we shall have would be an overall representation of all the features in the dataset. In this way, information loss can be minimised.
Now that we have understood the importance of PCA, we shall dive deeper to check if having 3 principal components and plotting them in a 3-Dimensional graph is more fruitful than having a 2 component PCA and a 2-Dimensional graph?
To keep things simple, I am not showing the dataset I have used, instead directly showing the three principal components which I obtained by using the PCA technique (with n=3) on my dataset.
The Principal Components are as follows
Principal component 1 Principal component 2 Principal component 3

You can see that I have 39020 tuples. Let us also look at the variance ratios for the three Principal Components.
The Variance Ratios are
[0.24679625 0.16479195 0.15822251]
Let us imagine that you are used to only 2-Component PCA and you haven’t got the 3rd Component in your analysis. Which now means in our scenario, you have only the first two principal components. Okay! Let us plot the first two principal components.

## A Wrapper for Sembast and SQFlite to Enable Easy

FHIR_DB

This is really just a wrapper around Sembast_SQFLite - so all of the heavy lifting was done by Alex Tekartik. I highly recommend that if you have any questions about working with this package that you take a look at Sembast. He's also just a super nice guy, and even answered a question for me when I was deciding which sembast version to use. As usual, ResoCoder also has a good tutorial.

I have an interest in low-resource settings and thus a specific reason to be able to store data offline. To encourage this use, there are a number of other packages I have created based around the data format FHIR. FHIR® is the registered trademark of HL7 and is used with the permission of HL7. Use of the FHIR trademark does not constitute endorsement of this product by HL7.

## Using the Db

So, while not absolutely necessary, I highly recommend that you use some sort of interface class. This adds the benefit of more easily handling errors, plus if you change to a different database in the future, you don't have to change the rest of your app, just the interface.

I've used something like this in my projects:

``````class IFhirDb {
IFhirDb();
final ResourceDao resourceDao = ResourceDao();

Future<Either<DbFailure, Resource>> save(Resource resource) async {
Resource resultResource;
try {
resultResource = await resourceDao.save(resource);
} catch (error) {
return left(DbFailure.unableToSave(error: error.toString()));
}
return right(resultResource);
}

Future<Either<DbFailure, List<Resource>>> returnListOfSingleResourceType(
String resourceType) async {
List<Resource> resultList;
try {
resultList =
await resourceDao.getAllSortedById(resourceType: resourceType);
} catch (error) {
return left(DbFailure.unableToObtainList(error: error.toString()));
}
return right(resultList);
}

Future<Either<DbFailure, List<Resource>>> searchFunction(
String resourceType, String searchString, String reference) async {
List<Resource> resultList;
try {
resultList =
await resourceDao.searchFor(resourceType, searchString, reference);
} catch (error) {
return left(DbFailure.unableToObtainList(error: error.toString()));
}
return right(resultList);
}
}
``````

I like this because in case there's an i/o error or something, it won't crash your app. Then, you can call this interface in your app like the following:

``````final patient = Patient(
resourceType: 'Patient',
name: [HumanName(text: 'New Patient Name')],
birthDate: Date(DateTime.now()),
);

final saveResult = await IFhirDb().save(patient);
``````

This will save your newly created patient to the locally embedded database.

IMPORTANT: this database will expect that all previously created resources have an id. When you save a resource, it will check to see if that resource type has already been stored. (Each resource type is saved in it's own store in the database). It will then check if there is an ID. If there's no ID, it will create a new one for that resource (along with metadata on version number and creation time). It will save it, and return the resource. If it already has an ID, it will copy the the old version of the resource into a _history store. It will then update the metadata of the new resource and save that version into the appropriate store for that resource. If, for instance, we have a previously created patient:

``````{
"resourceType": "Patient",
"id": "fhirfli-294057507-6811107",
"meta": {
"versionId": "1",
"lastUpdated": "2020-10-16T19:41:28.054369Z"
},
"name": [
{
"given": ["New"],
"family": "Patient"
}
],
"birthDate": "2020-10-16"
}
``````

And we update the last name to 'Provider'. The above version of the patient will be kept in _history, while in the 'Patient' store in the db, we will have the updated version:

``````{
"resourceType": "Patient",
"id": "fhirfli-294057507-6811107",
"meta": {
"versionId": "2",
"lastUpdated": "2020-10-16T19:45:07.316698Z"
},
"name": [
{
"given": ["New"],
"family": "Provider"
}
],
"birthDate": "2020-10-16"
}
``````

This way we can keep track of all previous version of all resources (which is obviously important in medicine).

For most of the interactions (saving, deleting, etc), they work the way you'd expect. The only difference is search. Because Sembast is NoSQL, we can search on any of the fields in a resource. If in our interface class, we have the following function:

``````  Future<Either<DbFailure, List<Resource>>> searchFunction(
String resourceType, String searchString, String reference) async {
List<Resource> resultList;
try {
resultList =
await resourceDao.searchFor(resourceType, searchString, reference);
} catch (error) {
return left(DbFailure.unableToObtainList(error: error.toString()));
}
return right(resultList);
}
``````

You can search for all immunizations of a certain patient:

``````searchFunction(
'Immunization', 'patient.reference', 'Patient/\$patientId');
``````

This function will search through all entries in the 'Immunization' store. It will look at all 'patient.reference' fields, and return any that match 'Patient/\$patientId'.

The last thing I'll mention is that this is a password protected db, using AES-256 encryption (although it can also use Salsa20). Anytime you use the db, you have the option of using a password for encryption/decryption. Remember, if you setup the database using encryption, you will only be able to access it using that same password. When you're ready to change the password, you will need to call the update password function. If we again assume we created a change password method in our interface, it might look something like this:

``````class IFhirDb {
IFhirDb();
final ResourceDao resourceDao = ResourceDao();
...
try {
} catch (error) {
}
return right(Unit);
}
``````

You don't have to use a password, and in that case, it will save the db file as plain text. If you want to add a password later, it will encrypt it at that time.

### General Store

After using this for a while in an app, I've realized that it needs to be able to store data apart from just FHIR resources, at least on occasion. For this, I've added a second class for all versions of the database called GeneralDao. This is similar to the ResourceDao, but fewer options. So, in order to save something, it would look like this:

``````await GeneralDao().save('password', {'new':'map'});
``````

The difference between these two options is that the first one will generate a key for the map being stored, while the second will store the map using the key provided. Both will return the key after successfully storing the map.

Other functions available include:

``````// deletes everything in the general store

// delete specific entry

// returns map with that key
``````

## Use this package as a library

### Depend on it

Run this command:

With Flutter:

`` \$ flutter pub add fhir_db``

This will add a line like this to your package's pubspec.yaml (and run an implicit flutter pub get):

``````dependencies:
fhir_db: ^0.4.3``````

### Import it

Now in your Dart code, you can use:

``````import 'package:fhir_db/dstu2.dart';
import 'package:fhir_db/dstu2/fhir_db.dart';
import 'package:fhir_db/dstu2/general_dao.dart';
import 'package:fhir_db/dstu2/resource_dao.dart';

🛠 Guide

## 📺 Demo

### 🔩 Basic Demo

``````// FButton #1
FButton(
height: 40,
alignment: Alignment.center,
text: "FButton #1",
style: TextStyle(color: Colors.white),
color: Color(0xffffab91),
onPressed: () {},
)

// FButton #2
FButton(
padding: const EdgeInsets.fromLTRB(12, 8, 12, 8),
text: "FButton #2",
style: TextStyle(color: Colors.white),
color: Color(0xffffab91),
corner: FCorner.all(6.0),
)

// FButton #3
FButton(
padding: const EdgeInsets.fromLTRB(12, 8, 12, 8),
text: "FButton #3",
style: TextStyle(color: Colors.white),
disableStyle: TextStyle(color: Colors.black38),

/// set disable Color
disabledColor: Colors.grey[300],
corner: FCorner.all(6.0),
)
``````

By simply configuring `text` and`onPressed`, you can construct an available FButton.

If `onPressed` is not set, FButton will be automatically recognized as not unavailable. At this time, ** FButton ** will have a default unavailable status style.

You can also freely configure the style of FButton when it is not available via the `disabledXXX` attribute.

### 🎈 Corner & Stroke

``````// #1
FButton(
width: 130,
text: "FButton #1",
style: TextStyle(color: Colors.white),
color: Color(0xffFF7043),
onPressed: () {},
clickEffect: true,

/// 配置边角大小
///
/// set corner size
corner: FCorner.all(25),
),

// #2
FButton(
width: 130,
text: "FButton #2",
style: TextStyle(color: Colors.white),
color: Color(0xffFFA726),
onPressed: () {},
clickEffect: true,
corner: FCorner(
leftBottomCorner: 40,
leftTopCorner: 6,
rightTopCorner: 40,
rightBottomCorner: 6,
),
),

// #3
FButton(
width: 130,
text: "FButton #3",
style: TextStyle(color: Colors.white),
color: Color(0xffFFc900),
onPressed: () {},
clickEffect: true,
corner: FCorner(leftTopCorner: 10),

/// 设置边角风格
///
/// set corner style
cornerStyle: FCornerStyle.bevel,
strokeWidth: 0.5,
strokeColor: Color(0xffF9A825),
),

// #4
FButton(
width: 130,
text: "FButton #4",
style: TextStyle(color: Colors.white),
color: Color(0xff00B0FF),
onPressed: () {},
clickEffect: true,
corner: FCorner(
rightTopCorner: 25,
rightBottomCorner: 25),
cornerStyle: FCornerStyle.bevel,
strokeWidth: 0.5,
strokeColor: Color(0xff000000),
),
``````

You can add rounded corners to FButton via the `corner` property. You can even control each fillet individually。

By default, the corners of FButton are rounded. By setting `cornerStyle: FCornerStyle.bevel`, you can get a bevel effect.

FButton supports control borders, provided that `strokeWidth> 0` can get the effect 🥳.

``````
FButton(
width: 100,
height: 60,
text: "#1",
style: TextStyle(color: Colors.white),
color: Color(0xffFFc900),

/// 配置渐变色
///
Color(0xff00B0FF),
Color(0xffFFc900),
]),
onPressed: () {},
clickEffect: true,
corner: FCorner.all(8),
)
``````

Through the `gradient` attribute, you can build FButton with gradient colors. You can freely build many types of gradient colors.

### 🍭 Icon

``````FButton(
width: 88,
height: 38,
text: "Back",
style: TextStyle(color: Colors.white),
color: Color(0xffffc900),
onPressed: () {
toast(context, "Back!");
},
clickEffect: true,
corner: FCorner(
leftTopCorner: 25,
leftBottomCorner: 25,),

/// 配置图标
///
/// set icon
image: Icon(
Icons.arrow_back_ios,
color: Colors.white,
size: 12,
),

/// 配置图标与文字的间距
///
/// Configure the spacing between icon and text
imageMargin: 8,
),

FButton(
onPressed: () {},
image: Icon(
Icons.print,
color: Colors.grey,
),
imageMargin: 8,

/// 配置图标与文字相对位置
///
/// Configure the relative position of icons and text
imageAlignment: ImageAlignment.top,
text: "Print",
style: TextStyle(color: textColor),
color: Colors.transparent,
),
``````

The `image` property can set an image for FButton and you can adjust the position of the image relative to the text, through`imageAlignment`.

If the button does not need a background, just set `color: Colors.transparent`.

### 🔥 Effect

``````
FButton(
width: 200,
text: "Try Me!",
style: TextStyle(color: textColor),
color: Color(0xffffc900),
onPressed: () {},
clickEffect: true,
corner: FCorner.all(9),

/// 配置按下时颜色
///
/// set pressed color
highlightColor: Color(0xffE65100).withOpacity(0.20),

/// 配置 hover 状态时颜色
///
/// set hover color
hoverColor: Colors.redAccent.withOpacity(0.16),
),
``````

The highlight color of FButton can be configured through the `highlightColor` property。

`hoverColor` can configure the color when the mouse moves to the range of FButton, which will be used during Web development.

``````FButton(
style: TextStyle(color: textColor),
color: Color(0xffffc900),
...

///

///
imageMargin: 6,

///

///

///

///

///
imageAlignment: ImageAlignment.top,
),

// #2
FButton(
width: 170,
height: 70,
style: TextStyle(color: textColor),
color: Color(0xffffc900),
onPressed: () { },
...
imageMargin: 8,

///
)

FButton(
width: 170,
height: 70,
alignment: Alignment.center,
style: TextStyle(color: Colors.white),
color: Color(0xff90caf9),
...
imageMargin: 8,

///
),
``````

Through the `loading` attribute, you can configure Loading effects for ** FButton **.

When FButton is in Loading state, FButton will enter an unavailable state, onPress will no longer be triggered, and unavailable styles will also be applied.

At the same time `loadingText` will overwrite`text` if it is not null.

The click start Loading effect can be achieved through the `clickLoading` attribute.

The position of `loading` will be affected by the`imageAlignment` attribute.

When `hideTextOnLoading: true`, if FButton is in`loading` state, its text will be hidden.

Through `loadingWidget`, developers can set completely customized loading styles.

``````
FButton(
width: 200,
textColor: Colors.white,
color: Color(0xffffc900),
onPressed: () {},
clickEffect: true,
corner: FCorner.all(28),

/// 配置阴影颜色
///

/// 设置组件高斯与阴影形状卷积的标准偏差。
///
/// Sets the standard deviation of the component's Gaussian convolution with the shadow shape.
),
``````

FButton allows you to configure the color, size, and position of the shadow.

### 🍭 Neumorphism Style

``````FButton(

/// 开启 Neumorphism 支持
///
/// Turn on Neumorphism support
isSupportNeumorphism: true,

/// 配置光源方向
///
/// Configure light source direction
lightOrientation: lightOrientation,

/// 配置亮部阴影
///

/// 配置暗部阴影
///
strokeColor: mainBackgroundColor,
strokeWidth: 3.0,
width: 190,
height: 60,
text: "FWidget",
style: TextStyle(
color: mainTextTitleColor, fontSize: neumorphismSize_2_2),
alignment: Alignment.center,
color: mainBackgroundColor,
...
)
``````

FButton brings an incredible, ultra-high texture Neumorphism style to developers.

Developers only need to configure the `isSupportNeumorphism` parameter to enable and disable the Neumorphism style.

If you want to adjust the style of Neumorphism, you can make subtle adjustments through several attributes related to Shadow, among which:

FButton also provides `lightOrientation` parameters, and even allows developers to adjust the care angle, and has obtained different Neumorphism effects.

😃 How to use？

Add dependencies in the project `pubspec.yaml` file:

## 🌐 pub dependency

``````dependencies:
fbutton: ^<version number>
``````

## 🖥 git dependencies

``````dependencies:
fbutton:

## Django security releases issued: 3.2.4, 3.1.12, and 2.2.24 | Weblog | Django

### Django security releases issued: 3.2.4, 3.1.12, and 2.2.24

Posted by Carlton Gibson  on Tháng 6 2, 2021

In accordance with our security release policy, the Django team is issuing Django 3.2.4Django 3.1.12, and Django 2.2.24. These release addresses the security issue detailed below. We encourage all users of Django to upgrade as soon as possible.

#### CVE-2021-33203: Potential directory traversal via admindocs

Staff members could use the admindocs TemplateDetailView view to check the existence of arbitrary files. Additionally, if (and only if) the default admindocs templates have been customized by the developers to also expose the file contents, then not only the existence but also the file contents would have been exposed.

As a mitigation, path sanitation is now applied and only files within the template root directories can be loaded.

This issue has low severity, according to the Django security policy.

Thanks to Rasmus Lerchedahl Petersen and Rasmus Wriedt Larsen from the CodeQL Python team for the report.

#### CVE-2021-33571: Possible indeterminate SSRF, RFI, and LFI attacks since validators accepted leading zeros in IPv4 addresses

URLValidatorvalidate_ipv4_address(), and validate_ipv46_address() didn’t prohibit leading zeros in octal literals. If you used such values you could suffer from indeterminate SSRF, RFI, and LFI attacks.

This issue has medium severity, according to the Django security policy.

#### Affected supported versions

• Django main branch
• Django 3.2
• Django 3.1
• Django 2.2

## Big Data Visualization: What, Why, Tips and Tools

Wondering what is big data visualization and how you can apply it for your business? Here's a guide to help you get started.

Because we live in a data-driven society, it’s likely that you’re constantly bombarded with complex sets of data that you need to transmit to your coworkers in an easy-to-grasp way.

The challenge is that almost no one wants to look at large lists of numbers and data, and important information can be easily lost within the midst of chaotic spreadsheets. But there is a solution, and that is big data visualization.

Today, we’ll be covering what big data visualization is and why it’s important, different big data visualization techniques you can use, tips and tricks for creating easily intelligible large data sets and the best big data visualization tools you can use.

By the end of this article, you’ll feel like a real data scientist and be competent in creating pie charts, bar charts, heat maps, histograms, interactive charts and more for big data visualization.

So let’s get into it, shall we?

What is Big Data Visualization?

Why is Data Visualization Important in Big Data?

What Are the Types of Big Data Visualization?

5 Big Data Visualization Tips for Beginners

4 Tools for Big Data Visualization

---

## What is Big Data Visualization?

Big data visualization is the representation of large sets of data through visual aids, whether that be through pie charts, heat maps, bar charts or any other kind of chart types or visual representation.

Analyzing and understanding large data sets and data analytics is no easy task and it can be especially difficult trying to relay that same information to colleagues who are not data-driven or data scientists.

That’s where big data visualization comes in. By transforming your large data sets into visually appealing infographics or interactive charts, you can easily convey your data points to fellow decision-makers.

When your data is plotted out on graphs in a visual way and metrics are made easily readable, no data gets lost in the mix, no matter how large or small, and it makes decision-making for the future a breeze.

Because you can’t make adequate decisions or advance significantly without analyzing your raw data, it’s important that companies use great data visualization methods to keep everyone in the loop.

Let’s take BMW for example.

Image Source

In 2020, BMW was able to track the number of sales for electric cars that they had and then compare it to other car companies’ sales, but not only.

They also were able to track the countries that bought the highest amount of their electric cars.

Image Source

This is a prime example of big data visualization in action. When you track your analytics and data, you can see where your wins are and when to celebrate or where your losses are and how you can make adjustments for the future.

Now, imagine for a moment that all this information was just written out plainly on a spreadsheet and had unstructured data all over it.

It would be hard to understand and assess how the company is doing and would take a long time to communicate to employees how their work has affected the sales of the cars.

This is why visualizing big data is so important. With just a glance and within seconds, you can easily see what cars are selling best and in what countries.

No time is wasted going through spreadsheets and trying to make sense of unstructured data — just visual analytics laid out for all to see and understand.

## Why is Data Visualization Important in Big Data?

We live in a time where the internet and social media have exploded at an extraordinary rate, and information can be gathered within seconds and at the tips of anyone’s fingers.

With the rise of this technological era, it’s important that data can be visualized and consumed quickly and efficiently — especially since the human brain now has an attention span of about 8 seconds, according to this study by the Technical University of Denmark.

Because companies, businesses and organizations can gather data more quickly than ever, this means that they need to be able to visualize that data in an equally quick and easily consumable way.

The best way to efficiently communicate your ever-coming, new data is through visualizing big data. This will bring your complex data to life and anyone who looks at it will be able to understand and grasp it with just a glance.

Customize this template and make it your own!

Take the image above as an example. With just a quick look at the statistics that are clearly visualized, you can make a data-based assumption.

Now, imagine if this data was just written out plainly on a spreadsheet. It would take much longer to understand and make an assumption based on the numbers.

By using big data visualization techniques, you’ll be able to get the most value from your data and analytics and make sure that everyone who says your data analysis will be able to interpret, understand and use your data. This, in turn, will help your company excel.

When you use data visualization techniques, it will optimize your use of data, help decision making and planning go smoothly, you’ll be able to identify and mitigate risk, extract loads of useful data and insights and improve your overall strategy and direction of your company.

There are no losses to using a visual representation of data, only wins. But there are lots of different types of data visualization that you can use.

Let’s discuss the different types of big data visualization and assess which one will work best for you.

## What Are the Types of Big Data Visualization?

There are lots of different types of data visualization that data analysts like to use and depending on the amount of data. A data analyst may choose to use a pie chart to express their numerical data or a bar chart.

When looking at big data analytics regarding locations, one might choose to use an interactive heat map or maybe a pivot table.

We’re going to look at 8 common types of big data visualization and some data visualization examples for each to help you decipher which one will work best for you.

### Type #1: Line Charts

Customize this template and make it your own!

A line chart, also known as a line graph, is a graphic representation of data that plots a fixed value on one side and a variable on the other.

A line chart is a fantastic way to represent the relationship of data. You can use a line chart to represent changes and fluctuations of things within a certain period of time.

### Type #2: Bar Charts

Customize this template and make it your own!

A bar chart, also known as a bar graph, uses bars to compare different data points or data sets.

Many data scientists will use bar charts to visually represent their data analysis. You can use a bar chart to compare large amounts of data, fluctuations of quantities or different categories.

The taller the bar, the larger the numerical value and vice versa.

### Type #3: Pie Charts

Customize this template and make it your own!

Pie charts, donut charts, circle graphs or whatever you choose to call them, are representations of data that are split into smaller segments and sizes to represent their numerical value.

When you use a pie chart, it becomes easy to see and compare how the different segments relate and differ from each other.

When using a pie chart, try not to overload it with too many different values. When you split the pie chart into more than 7 segments, it can become difficult to understand the data.

### Type #4: Heat Maps

Image Source

A heat map is a visual representation of data that is laid out on a map or table and uses different nuances and intensities of colors to represent its data.

Using a heat map can be especially helpful when you need to analyze data that seems to be never-ending. When you have an extremely wide value range, using a heat map makes it much more simple to quickly visualize and analyze large amounts of complex data at a glance.

### Type #5: Histograms

Customize this template and make it your own!

A histogram is a graphical and visual representation of complex data sets and the frequency of said numerical data displayed through bars.

Histograms are very similar to bar graphs but vary in the fact that they mostly focus on the repeated frequency of numerical data.

### Type #6: Scatter Plots

Customize this template and make it your own!

A scatter plot, scatter chart or scatter graph, is a diagram that uses dots to represent and emphasize the different values of two or more numeric variables on an X and Y-axis.

Scatter plots are extremely useful to use when you have multiple large data sets and you want to know how they relate to each other and compare the importance of each value.

### Type #7: Treemaps

Create your own charts and graphs!

Treemaps are the visual representation of hierarchical data by using color-coded rectangles.

Users can use treemaps as a method to compare multiple sets of data and reflect the weight of each value in a project.

### Type #8: Funnel Charts

Customize this template and make it your own!

Funnel charts are typically used in sales and represent the different stages that your users or customers go through during the sales process and demonstrate decreasing values as they move through your funnel.

By using a funnel chart, you can accurately see where you are losing or gaining your customers during the sales process.

## 5 Big Data Visualization Tips for Beginners

Now that we’ve covered what big data visualization is, its importance and 9 different types of data visualization, you may feel like you’re a professional in data science.

Now that you’re familiar with the basics of data visualization, it’s time that we equip you with some of our best data visualization techniques.

Here are our top 5 best data visualization techniques for you to use when creating a visual representation of your data.

### Tip #1: Use a Powerful Data Visualization Tool

Customize this template and make it your own!

You can’t create powerful graphs without a powerful data visualization tool.

Sure, you could use something like Google charts, but to create unique, engaging charts, you’ll want to use a data visualization tool like Visme that's packed with amazing functionality.

Visme is a powerful data visualization tool with many integration functionalities. As you can see in the image above, you can create everything from funnel charts and tables to interactive data maps and graphs in this editor.

It’s important to use a strong data visualization software for your data analysis and presentations. Stick around and soon we’ll get into our list of best tools for big data visualization.

### Tip #2: Pick the Correct Form of Big Data Visualization

Customize this template and make it your own!

When it comes to visualizing your data, you need to make sure that you choose the correct chart type.

Because there are so many different ways to display your data, you need to weigh out the cons and pros of each and find out which one will work best for your infographic or presentation.

Take for example pie charts and bar graphs.

When you analyze data that is very different, you might want to use a pie chart. But if you want to represent data entries that are close together, you could use a bar chart for that.

If you’re trying to create data visualization for sales, you could use a funnel chart, pyramid chart or cone chart for that.

Each different visualization method has its time and place, and you need to analyze your data and think about what method will work best for your respective data.

Refer above to the “Big Data Visualization Types” section above to see which one will suit you best.

### Tip #3: Make Sure Your Data is Easily Comprehensible

Customize this template and make it your own!

The whole point of big data visualization is to make it easy to understand at a glance.

It won’t be easily intelligible if you just start piling in large amounts of unstructured data and simply hope for the best. Or imagine you have tens of tiny little numbers on a bar graph that no one can see or read.

You need to make sure that anyone on your team, whether a data scientist or not, can understand what you’re trying to convey at a glance.

You can do this by using clear and bold text, contrasting font colors and background colors, not adding too many values to one chart and using compelling images to highlight your point, just like in the example above.

By adding too much text or too many values to a single graph, you risk confusing your audience even more. So keep it as simple and concise as possible.

### Tip #4: Always Use Legends to Further Explain Your Data

Customize this template and make it your own!

Using legends is absolutely vital for making your data easy to understand, so whether you’re creating a pie chart or bar graph, make sure you’re using a legend.

A legend is an area of your design that further explains each segment of your chart.

Many times people will assign a color to a segment in their chart, just like in the example above, and on the side add a little graphic element that explains what each color represents.

The legend is responsible for keeping the audience engaged and understanding everything you’re trying to convey.

### Tip #5: Use Multiple Charts for Big Data

Visualize big data easily with this drag-and-drop tool!

If you have a large amount of data that needs to be conveyed to your team, try using multiple graphs to do so.

Incorporating tons of data into a single chart will only make it hard for the human brain to stay on track and focus to try and understand what you want to share.

The best rule of thumb to follow here is KISS — keep it simple, stupid.

So instead of simply adding all your data to one pie chart and making it have 30 pie slices, why not create multiple graphs and break it down into bite-sized pieces? Pun intended.

By creating multiple matching charts, you can keep your data easily intelligible, cohesive and right on brand.

Just like in the example above, you can clearly understand all the data that’s being displayed because it is written out on two different donut charts.

You want to make sure your information is understandable by anyone at a glance, and you can do so by breaking down your data.

## 4 Tools for Big Data Visualization

Now that you know essentially all there is to know about big data visualization, it’s time you choose a tool that will help you create those visuals.

Video is powerful for a few reasons.

First, it allows you to demonstrate concepts faster and more clearly. For example, when you’re watching a video, you’re using your sense of hearing and your sense of sight together, creating a rich learning experience. Whereas text-based content limits you to just sight.

Second, video allows you to create a personal connection with viewers, which shouldn’t be undermined

## MY OPINION: IS IT WORTH USING?

The difference between a 360 degree video and a normal video is that with a 360 degree video, you – the viewer – get far more control over what you get to look at.

So you can move around the scene and basically pick something that takes your interest whereas with a normal video, you’re in the hands of whoever put the video together to decide what it is you get to see.

The thing that makes 360 degree video really interesting is that it can be experienced in a variety of different ways. The most common one probably being on your computer where you use your mouse to click and drag around the scene. but where it starts to get a bit more interesting is when you use your smartphone or tablet.

Using something like the YouTube app you can move your device around and it will move as if you were actually there and a lot of these apps will let you use a headset which pushes 360-degree video into the realm of virtual reality.

If you put your headset on and watch it, it’s almost as if you were there. Especially if the 360 degree video was filmed in 3D. It’s really immersive. In the past, creating 360 degree videos required specialty camera rigs and really complex post-production techniques but nowadays, it’s not so anymore.

My aim with this VideoTours360 Ultimate Review article is to review an immersive 360 degree video app that leverages the ‘Zero touch’ trend in the new post covid economy where customers don’t want to leave their homes. With this app, you can create beautiful and highly-engaging 360 videos in just a couple of minutes – WITHOUT any sort of special skills or knowledge.

Just before the app went live, I got a review access to VideoTours360 Ultimate from the product creator a few days ago. There ‘s this buzzing rave in the online community about the app so I got curious and decided to do an in depth review

So this section of VideoTours360 Ultimate Review will serve to either validate or discredit the buzz this bad boy is getting all over the internet. So do stick around for a minute or two, I promise you’ll be getting a professional insight into this software… this will give enough information needed to make an informed purchase decision.

First, I’ll do a detailed overview of the offer and all that it comes with plus the problem it solves, then I’ll give a highlight of all it’s features and tools. Afterward, we’ll check out the true cost of the offer, the upsells (and if they complement the front end offer or not), then we’ll see who should take advantage of this offer.

Then the pros, the cons and finally an overall verdict. I believe this review article will help you make an informed purchase decision and get the best deal for your money, so hang on!

## VIDEOTOURS360 ULTIMATE REVIEW – FINAL VERDICT

From all that has been said, the value proposition is quite clear as it solves a true pressing and expensive problem.

If we come from the angle of outsourcing 360 degree video creation for your car sales, real estate property showcase and ecommerce products then you will have to pay for every new product you want to put out for sales which means sending thousands of dollars every month.

The least you will be charged for a good 360 degree video is about a \$100 just be very conservative. Imagine you have 10 new property listings every month, that like paying \$1000 every month for a relatively high quality video.

if you even hire big video agencies to create high quality 360 degree videos then expect to pay nothing less than \$1000 for just one video. That’s expensive … right?

The bad part is they not include the other features like adding a hotspots to your tours, collect emails of your visitors or even going viral with your videos. So you see the true worth of the problem this software solves?

To be fair, I’ll have said VideoTours360 Ultimate is easily worth \$297/Month . . . but for the added Inbuilt viral engine and AI machine to analyze the behavioural patterns of your visitors which opens a true opportunity to every user, then VideoTours360 Ultimate is fairly worth \$497 – \$997 per month.

Before I give my final thoughts, which I think is already obvious by now, I’ll like to say one or two things about the product creator and product vendor.

First, Ifiok NK is the CEO SnapiLABs Inc., a fast-rising software company responsible for a number of bestseller software platforms and solutions to real-life problems(just like VideoTours360 Ultimate.)

SnapiLABs has a fulltime team of developers and support personnel, hence their unmatched reputation in customer support and software maintenance.

Ifiok was vetted by Forbes & accepted into their prestigious Business Council in recognition of his track record of successfully impacting entrepreneurs & small businesses, industry leadership as well as personal and professional achievements.

Some of the software platforms by this serial creator are ContentBurger, Socicake, DesignBundle, Uduala, ConvertProof and a host of others.

I found VideoTours360 Ultimate really easy to use when building my first ever virtual tour, yet flexible and powerful enough to implement quite extensive projects. I’ve tested the virtual tours across multiple device types and browsers, and it just works – without any technical headaches.

It allows me to me to focus on the design aspects, without having to learn to be a web developer. The customer service and platform reliability have both been excellent since and there is constant development of new features.

Fantastic in every respect. I’m building amazing tours that my clients love. Because of the high degree of customization, I get to really express my creativity in each tour. I also like the streamlined workflow which enables me to get even complex tours in under deadlines.

We experimented with a number of platforms but they did not have the ease of use and versatility VideoTours360 Ultimate offer. They have everything you need to produce a virtual tour and make it as basic, complex or as intuitive as you like.

Really good created User Experience on the site. Everything working fast, intuitive, and without problems. Everything that was needed, we wrote on support and they help up under 24 hours.

There is an inspiring community producing amazing interactive content though the platform and the VideoTours360 Ultimate team is extremely supportive in promoting our content and increasing global awareness.

Hence, on this note, I’ll say; VideoTours360 Ultimate is a timely solution and I highly recommend it. Without any doubt, I can give it a five-star review, anything other than that will be “BIAS!” You can go ahead and secure your access, your investment is SAFE & WISE, cheers!
