Choosing the right JavaScript charting library from the thousands available can be a daunting task. To help, I’ve put together a list of the best JavaScript charting libraries, including their strengths, weaknesses, pricing models, and supported chart types.

1. 1. Best JavaScript Charting Libraries

1. 1. 1. 1. Chart.js

Chart.js is an open-source JavaScript library that supports eight chart types: bar, line, area, pie (doughnut), bubble, radar, polar, and scatter. This library is very easy to use for developers who are just starting with JavaScript charting, as it’s one of the simplest libraries to set up.

Chart.js needs the Moment.js library to work with time axes. However, if you don’t need time axes, you can use a lightweight build of Chart.js (e.g. Chart.bundle.js or Chart.min.js) that doesn’t include Moment.js.

Chart.js is free and open source and maintained by an active community. However, as it’s a community-driven project, there’s no official support for it. The lack of official support and the limited number of chart types mean that this library isn’t suitable for enterprise use.

1. 1. 1. 2. D3.js

D3.js is a JavaScript library for manipulating DOM objects based on data. While it’s not a charting library in itself, D3.js is frequently used for visualization purposes as it allows you to bind data to the DOM and apply data-driven transformations. Developers can use D3.js to create almost any type of chart (e.g. hierarchical, relational, or spatial), as well as advanced data visualizations (e.g. chord diagrams, node-link diagrams, or word clouds).

D3.js is open source and free to use. However, it has a steep learning curve and isn’t suitable for developers who need to quickly create charts or have no previous experience with JavaScript charting. In addition, D3.js doesn’t work with older versions of Internet Explorer (IE8 and below). As D3.js is a community-driven project as well, there’s no official support for it.

1. 1. 1. 3. Highcharts

Highcharts is a JavaScript charting library that supports 39 basic and advanced chart types, such as bar, column, spline, area, pie, bubble, and gauges, as well as specialized charts, such as heat and tree maps.
