Introduction

In the simplest terms, data visualization refers to how we represent our data with visuals like charts, graphs, and so on. It is the representation of data in graphical format, usually a mapping or a relationship between data points and lines of a chart or graph. Generally, it entails designing the right visual interface for our data.

The form of the visualization usually depends on the relationship between the chosen graphical elements or types and the data points involved. The end goal is to communicate information derived from data sources clearly and effectively via visual or graphical means.

Data viz, as it is sometimes called, is particularly useful to help us tell stories about our data and, in the process, understand the representation of a large set of data point at a glance. Essentially, representing data in an aesthetically pleasing and easily consumable way are the major goals of data viz.

When it comes to very large and complex datasets, the functionality of the data viz library at play is also important for effective insights. In this tutorial, we are going to be looking at some of JavaScript’s data visualization libraries and how they compare.

Exploring data viz libraries in JavaScript

These days, almost every application we build requires or leverages data to enhance the functionality provided to users. There are a plethora of JavaScript libraries for data visualization available today. Therefore, finding the right one is very crucial in easing our development process.

In this post, we’ll explore some common data visualization libraries in JavaScript:

• Highcharts
• Toast UI Chart
• D3.js
• Recharts
• Chart.js

We’ll compare their pros and cons, key features and functionalities, philosophy, and so on. At the end of the day, the goal is to understand why we might pick one of these visualization libraries based on their available features and our particular use case.

Now let’s highlight these libraries in turn below
