24 JavaScript Libraries for Creating Beautiful Charts

24 JavaScript Libraries for Creating Beautiful Charts

In this article, I’ll show you some of the best JavaScript libraries for graphs / charts. These libraries will help you create beautiful and customisable charts for your future projects.

It’s practically impossible to imagine any dashboard without graphs and charts. They present complex statistics quickly and effectively. Additionally, a good graph also enhances the overall design of your website.


While most of the libraries are free and open source, some of them provide a paid version with additional features.


D3.js — Data-Driven Documents

When we think of charting today, D3.js is the first name that comes up. Being an open source project, D3.js definitely brings many powerful features that were missing in most of the existing libraries. Features like “Enter and Exit”, powerful transitions and syntax familiarity with jQuery or Prototype make it one the best JavaScript libraries for charting. Charts in D3.js are rendered via HTML, SVG and CSS.

Unlike many other JavaScript libraries, D3.js doesn’t ship with any pre-built charts out of the box. However, you can look at the list of graphs built with D3.js to get an overview.

D3.js doesn’t work well with older browsers like IE8. You can always use plugins like aight plugin for cross browser compatibility.

Websites like NYTimes, Uber and Weather.com have used D3.js extensively in the past.


Google Charts

Google Charts is my go-to JavaScript library for creating charts easily. It provides many pre-built charts like area charts, bar charts, calendar charts, pie Charts, geo charts, and more.

Google charts also comes with various customization options that help in changing the look of the graph. Charts are rendered using HTML5/SVG to provide cross-browser compatibility and cross platform portability to iPhones, iPads, and Android. It also includes VML for supporting older IE versions.

Here’s a great list of examples built using Google charts.


ChartJS

ChartJS provides beautiful flat designs for charts. It uses HTML5 canvas element for rendering. Support for older browsers like IE7/8 is added through polyfill.

ChartJS charts are responsive by default. They work well in mobiles and tablets. With 6 different types of core charts out of the box (core, bar, doughnut, radar, line, and polar area), ChartJS is definitely one of the most impressive open source charting libraries in recent times.


Chartist.js

Chartist.js provides beautiful responsive charts. Just like ChartJS, Chartist.js is also the product of the community that was frustrated by using highly priced JavaScript charting libraries. It uses SVG to render the charts. It can be controlled and customised through CSS3 media queries and Sass. Also, note that Chartist.js provides cool animations that will work only in modern browsers.


n3-charts

If you are an Angular developer, you will definitely find n3-charts extremely useful and interesting. n3-charts is built on top of D3.js and Angular. It provides various standard charts in the form of customisable Angular directives.

Checkout list of charts built using ns-charts.


Ember Charts

Ember Charts is another great open source repository built with D3.js and Ember.js. It provides time series, bar, pie, and scatter charts that are easily customisable. It uses SVG to render charts.


Smoothie Charts

If you are dealing with stream realtime data, Smoothie Charts may be helpful. It uses HTML5 canvas element to render the chart. It is a pure JavaScript library that provides options like delay and splash colors to the realtime graphs.


Chartkick

Chartkick is a JavaScript charting library built for Ruby applications. It provides all the major chart types like pie, column, bar, area, geo, timeline, and multiple series. The charts render via SVG.


ZingChart

ZingChart offers a flexible, interactive, fast, scalable and modern product for creating charts quickly. Their product is used by companies like Apple, Microsoft, Adobe, Boeing and Walmart, and uses Ajax, JSON, HTML5 to deliver great-looking charts quickly.

Free to try, ZingChart licenses can also be bought at a variety of price-points to suit your business size.


Highcharts JS

Highcharts JS is another very popular library for building graphs. It comes loaded with many different types of cool animations that are sufficient to attract many eyeballs to your website. Just like other libraries, Highcharts comes with many pre-built graphs like spline, area, areaspline, column, bar, pie, scatter, etc.

One of the biggest advantages of using Highcharts JS is the compatibility with older browsers — even way back to Internet Explorer 6. Standard browsers use SVG for the graphics rendering. In legacy Internet Explorer, graphics are drawn using VML.

While Highcharts JS is free for personal use, you need to purchase a license for commercial usage.


Fusioncharts

Fusioncharts is one of the oldest JavaScript charting libraries, released way back in 2002. Charts are rendered using HTML5/SVG and VML for better portability and compatibility.

Unlike many libraries, Fusioncharts provides data parsing through both JSON and XML. You can also export these charts in three different formats — PNG, JPG and PDF.

Fusioncharts is highly compatible with older browsers — even way back to Internet Explorer 6. This backwards compatibility made it a very popular choice for a long time.

You can use the watermarked version of Fusioncharts for free in both personal and commercial projects. However, you need to purchase a license to remove the watermark.


Flot

Flot is a JavaScript charting library for jQuery. It is also one of the oldest and popular charting libraries.

Flot supports lines, points, filled areas, bars and any combinations of these. It’s also compatible with older browsers — way back to IE6 and Firefox 2.

Flot is completely free to use and commercial support is provided on special request to the creator. It’s maybe getting a bit old now (the last commit was in 2014) but it’s still worth checking out. Here’s a list of example graphs created using Flot.


amCharts

amCharts is undoubtedly one of the most beautiful charting libraries out there. It perfectly segregates itself into 3 independent charts — JavaScript Charts, Maps Charts (amMaps), and Stock charts.

amMaps is my favorite out the above three. It provides features like loading icons or photos on top of your map, heatmaps, drawing lines, and adding text on maps, zooming and others.

amCharts uses SVG to render charts that work in modern browsers.

Checkout this fantastic collection of cool demos created using amCharts.

The free version of amChart will leave a backlink to its website on the top of every chart. The commercial licenses are bit more expensive than most of the paid libraries in the market.


EJSCharts

EJSCharts is the open source solution for home and business data representation and customization. The makers describe it as an enterprise ready charting library. The charts look clean and readable than most of the older charting libraries. Check out this list of examples.

EJSCharts comes in free and paid versions. The free version limits you to use maximum of 1 chart per page and 2 series per chart. Have a look at the pricing details here.


uvCharts

uvCharts is an open source JavaScript charting library that claims to have 100+ customization options. It has 12 different standard chart types out of the box.

uvCharts is built using D3.js library. It promises to eliminate all the difficult coding parts from D3.js and provide easy implementations of standard chart types. uvCharts are rendered using SVG, HTML and CSS.


Plotly.js

Plotly.js is the first scientific JavaScript charting library for the web. It has been open-source since 2015, meaning anyone can use it for free. Plotly.js supports 20 chart types, including histograms, 3d plots, error bars, and maps. It can also do all of the basic charts like bar charts, line charts, and pies.

Plotly.js uses D3.js under-the-hood, so its an easier way to make D3.js graphs than using D3.js by itself. For some examples of graphs made with Plotly.js, check out Plotly’s graph news feed.


Conclusion

It now depends on you to select the best charting library for your future projects. Developers who like to have all the controls over their charts will definitely opt for D3.js. Almost all the above libraries have got a good support via Stack Overflow forums.

If you are looking for tools to generate ready made charts, head over to 5 Tools for Creating Amazing Online Charts article. You can also read Creating Simple Line and Bar Charts Using D3.js article to get started with D3.js. We also have a dedicated series on using Google Charts with Angular.

JavaScript Tutorial: if-else Statement in JavaScript

JavaScript Tutorial: if-else Statement in JavaScript

This JavaScript tutorial is a step by step guide on JavaScript If Else Statements. Learn how to use If Else in javascript and also JavaScript If Else Statements. if-else Statement in JavaScript. JavaScript's conditional statements: if; if-else; nested-if; if-else-if. These statements allow you to control the flow of your program's execution based upon conditions known only during run time.

Decision Making in programming is similar to decision making in real life. In programming also we face some situations where we want a certain block of code to be executed when some condition is fulfilled.
A programming language uses control statements to control the flow of execution of the program based on certain conditions. These are used to cause the flow of execution to advance and branch based on changes to the state of a program.

JavaScript’s conditional statements:

  • if
  • if-else
  • nested-if
  • if-else-if

These statements allow you to control the flow of your program’s execution based upon conditions known only during run time.

  • if: if statement is the most simple decision making statement. It is used to decide whether a certain statement or block of statements will be executed or not i.e if a certain condition is true then a block of statement is executed otherwise not.
    Syntax:
if(condition) 
{
   // Statements to execute if
   // condition is true
}

Here, condition after evaluation will be either true or false. if statement accepts boolean values – if the value is true then it will execute the block of statements under it.
If we do not provide the curly braces ‘{‘ and ‘}’ after if( condition ) then by default if statement will consider the immediate one statement to be inside its block. For example,

if(condition)
   statement1;
   statement2;

// Here if the condition is true, if block 
// will consider only statement1 to be inside 
// its block.

Flow chart:

Example:

<script type = "text/javaScript"> 

// JavaScript program to illustrate If statement 

var i = 10; 

if (i > 15) 
document.write("10 is less than 15"); 

// This statement will be executed 
// as if considers one statement by default 
document.write("I am Not in if"); 

< /script> 

Output:

I am Not in if
  • if-else: The if statement alone tells us that if a condition is true it will execute a block of statements and if the condition is false it won’t. But what if we want to do something else if the condition is false. Here comes the else statement. We can use the else statement with if statement to execute a block of code when the condition is false.
    Syntax:
if (condition)
{
    // Executes this block if
    // condition is true
}
else
{
    // Executes this block if
    // condition is false
}


Example:

<script type = "text/javaScript"> 

// JavaScript program to illustrate If-else statement 

var i = 10; 

if (i < 15) 
document.write("10 is less than 15"); 
else
document.write("I am Not in if"); 

< /script> 

Output:

i is smaller than 15
  • nested-if A nested if is an if statement that is the target of another if or else. Nested if statements means an if statement inside an if statement. Yes, JavaScript allows us to nest if statements within if statements. i.e, we can place an if statement inside another if statement.
    Syntax:
if (condition1) 
{
   // Executes when condition1 is true
   if (condition2) 
   {
      // Executes when condition2 is true
   }
}

Example:

<script type = "text/javaScript"> 

// JavaScript program to illustrate nested-if statement 

var i = 10; 

if (i == 10) { 

// First if statement 
if (i < 15) 
	document.write("i is smaller than 15"); 

// Nested - if statement 
// Will only be executed if statement above 
// it is true 
if (i < 12) 
	document.write("i is smaller than 12 too"); 
else
	document.write("i is greater than 15"); 
} 
< /script> 

Output:

i is smaller than 15
i is smaller than 12 too
  • if-else-if ladder Here, a user can decide among multiple options.The if statements are executed from the top down. As soon as one of the conditions controlling the if is true, the statement associated with that if is executed, and the rest of the ladder is bypassed. If none of the conditions is true, then the final else statement will be executed.
if (condition)
    statement;
else if (condition)
    statement;
.
.
else
    statement;


Example:

<script type = "text/javaScript"> 
// JavaScript program to illustrate nested-if statement 

var i = 20; 

if (i == 10) 
document.wrte("i is 10"); 
else if (i == 15) 
document.wrte("i is 15"); 
else if (i == 20) 
document.wrte("i is 20"); 
else
document.wrte("i is not present"); 
< /script> 

Output:

i is 20

How to Retrieve full Profile of LinkedIn User using Javascript

How to Retrieve full Profile of LinkedIn User using Javascript

I am trying to retrieve the full profile (especially job history and educational qualifications) of a linkedin user via the Javascript (Fetch LinkedIn Data Using JavaScript)

Here we are fetching LinkedIn data like Username, Email and other fields using JavaScript SDK.

Here we have 2 workarounds.

  1. Configuration of linkedIn developer api
  2. Javascript Code to fetch records

Configuration of linkedIn developer api

In order to fetch records, first we need to create developer api in linkedin which will act as token/identity while fetching data from other linkedin accounts.

So to create api, navigate to https://linkedin.com/developer/apps and click on 'Create Application'.

After navigating, fill in details like name, description and other required fields and then submit.

As we submit, it will create Client ID and Client Secret shown below, which we will be using in our code while communicating to fetch records from other LinkedIn account.

Note: We need to provide localhost Url here under Oauth 2.0. I am using my localhost, but you can probably use other production URLs under Oauth 2.0 where your app is configured. It will make your api  consider the Url as trusted which fetching records.

Javascript Code to fetch records

For getting user details like first name, last name,User image can be written as,

<script type="text/javascript" src="https://platform.linkedin.com/in.js">  
    api_key: XXXXXXX //Client ID  
    onLoad: OnLinkedInFrameworkLoad //Method that will be called on page load  
    authorize: true  
</script>  
<script type="text/javascript">  
    function OnLinkedInFrameworkLoad() {  
        IN.Event.on(IN, "auth", OnLinkedInAuth);  
    }  
  
    function OnLinkedInAuth() {  
        IN.API.Profile("me").result(ShowProfileData);  
    }  
  
    function ShowProfileData(profiles) {  
        var member = profiles.values[0];  
        var id = member.id;  
        var firstName = member.firstName;  
        var lastName = member.lastName;  
        var photo = member.pictureUrl;  
        var headline = member.headline;  
        //use information captured above  
        var stringToBind = "<p>First Name: " + firstName + " <p/><p> Last Name: " + lastName + "<p/><p>User ID: " + id + " and Head Line Provided: " + headline + "<p/>"  
        document.getElementById('profiles').innerHTML = stringToBind;  
    }  
</script>    

Kindly note we need to include 'https://platform.linkedin.com/in.js' as src under script type as it will act on this Javascript SDK provided by Linkedin.

In the same way we can also fetch records of any organization with the companyid as keyword.

<head>  
    <script type="text/javascript" src="https://platform.linkedin.com/in.js">  
        api_key: XXXXXXX ////Client ID  
        onLoad: onLinkedInLoad  
        authorize: true  
    </script>  
</head>  
  
<body>  
    <div id="displayUpdates"></div>  
    <script type="text/javascript">  
        function onLinkedInLoad() {  
            IN.Event.on(IN, "auth", onLinkedInAuth);  
            console.log("On auth");  
        }  
  
        function onLinkedInAuth() {  
            var cpnyID = XXXXX; //the Company ID for which we want updates  
            IN.API.Raw("/companies/" + cpnyID + "/updates?event-type=status-update&start=0&count=10&format=json").result(displayCompanyUpdates);  
            console.log("After auth");  
        }  
  
        function displayCompanyUpdates(result) {  
            var div = document.getElementById("displayUpdates");  
            var el = "<ul>";  
            var resValues = result.values;  
            for (var i in resValues) {  
                var share = resValues[i].updateContent.companyStatusUpdate.share;  
                var isContent = share.content;  
                var isTitled = isContent,  
                    isLinked = isContent,  
                    isDescription = isContent,  
                    isThumbnail = isContent,  
                    isComment = isContent;  
                if (isTitled) {  
                    var title = isContent.title;  
                } else {  
                    var title = "News headline";  
                }  
                var comment = share.comment;  
                if (isLinked) {  
                    var link = isContent.shortenedUrl;  
                } else {  
                    var link = "#";  
                }  
                if (isDescription) {  
                    var description = isContent.description;  
                } else {  
                    var description = "No description";  
                }  
                /* 
                if (isThumbnailz) { 
                var thumbnailUrl = isContent.thumbnailUrl; 
                } else { 
                var thumbnailUrl = "http://placehold.it/60x60"; 
                } 
                */  
                if (share) {  
                    var content = "<a target='_blank' href=" + link + ">" + comment + "</a><br>";  
                    //el += "<li><img src='" + thumbnailUrl + "' alt=''>" + content + "</li>";  
                    el += "<li><div>" + content + "</div></li>";  
                }  
                console.log(share);  
            }  
            el += "</ul>";  
            document.getElementById("displayUpdates").innerHTML = el;  
        }  
    </script>  
</body>  

We can get multiple metadata while fetching records for any any organization. We can get company updates as shown below.

Conclusion

We can also fetch any company specific data like company job updates/post, total likes, comments, and number of views along with a lot of metadata we can fetch which I have shown below.
