Advancements in browser based technologies like JS, CSS, HTML5, WebGL and use of SVG for graphics has given real powers in the hands of JavaScript developers to create stunning visual effects and spice up graphs and charts rendering. There are many data visualization tools and resources to create graphs and charts but nothing does it better than the specialized JavaScript libraries like D3.js, Google Charts, Cytoscape.js, HighCharts & Amcharts, to name a few.

Let us look at the best of JavaScript libraries for Charts and graphs that make data visualization a real breeze.

Most of the JavaScript charting libraries covered in this article are available as open source and free to use, but I have covered some paid libraries as well, that are too good to be avoided.

D3.JS a.k.a Data Driven Documents

D3js is the most popular and powerful open source JavaScript library for charts and graphs. You can easily call D3 as the big daddy in the data visualization space. When it comes to learning D3js, there are tons of resources available around the web and a very helpful community to get you started within no time. D3.js injects life to raw data by manipulating HTML, CSS and SVG.

D3 complies with web standards and is extremely fast in creating interactive and animated data visualization components using large data sets.

The ecosystem of D3.JS has grown too huge that you find hundreds of plugins and supporting libraries built on top of D3JS. One of the biggest reason for existence of huge list of plugins and supporting libraries is the modular core design of D3.JS that allows code reuse and extension without breaking the core.

There are other commercial libraries like FusionCharts and HighCharts that compete with D3.JS and can be used for creating enterprise grade charts and graphs, but none of the mentioned two are free to use for commercial applications.

The popularity and power of HighCharts can be known from the fact that these have been used by the biggies like Facebook and Twitter. Highcharts being a commercial product, offers a lot more than just a data visualization library, one of the good features of Highcharts is “Highcharts Cloud”,, that offers online charts editor and hosting platform.

Google Charts

It wont be wrong to say that any product from the house of google is for the masses. Google Charts is one of my favorite libraries for all my charting needs. Google charts library is open source and available free to use under creative commons attribution 3.0 license.

With Google charts you can create simple scatter plots as well as hierarchical treemaps, HTML5/SVG based, cross browser compatible, without the need of additional plugins.

With just a few simple steps one can add interactive Google charts to any webpage. Many of these charts come with out of the box zoom and pan functionality. You can also extend other basic charts to add more features, as per the data visualization needs.

When you use Google charts for data visualization, the possibilities are nearly endless, you can always use out of the box charts, customize and develop your own charts or use community contributed charts.

There is no dearth of JavaScript Libraries when it comes to creating charts and graphs. Identification of one for your projects really depends on your design and development style, skillset and the features offered by these libraries.

Libraries mentioned in this article have great resources and big ecosystem to get you started within no time. You can easily find tutorials, documentation as well as fully functional code snippets for reference.

As per the needs of your project, you can pick a library that provides ready to use charts and graphs but offer lesser flexibility as well as libraries that let you build your own charts with full flexibility and customization options in your hands.
