You can get started with simple and free charting libraries like Chart.js, Echarts, Chartist, N3-charts, EJS Charts and JScharts etc or go ahead with commercial products like Highcharts.js, Fusion charts, ZingChart or AmCharts.
The answer to this question depends on many factors including your liking, skill level, learning curve, input data formats, chart types required, interactivity level required, performance, 2D or 3D, targeted browsers, targeted platforms, and of course budget at hand.
If your requirements are limited to embedding few simple charts on your website or blog, or if you are a student working on some university report project etc, the answer gets very simple – go for an open source and free library like Chart.js, JScharts, D3.js or Google Charts, and there are many more.
While libraries like D3.js, Echarts and Google charts are free, they are real powerful and feature rich and are widely used for enterprise grade projects too.
On the other side, if you are working for a large organization, chances are that you won’t have much of a constraint on the budget. If that is so, there are few good options including names like Highcharts, Fusion Charts, ZingChart and AmCharts.
Our team has gone through various charting libraries, so you don’t have to try them all, listed below are the best libraries for charts and a summary of the key features –
D3.js is more of a library for developers than designers, data scientists or business analysts. D3 is modular and extensible, and there are many modules and ready to use charts built on top of D3, by community of developers. You can check out the list of D3 npm Modules here.
