Chart.js

+

Easy, object oriented client side graphs for designers and developers

+
+ + + + DocumentationDownload +
+
+
+ +

6 Chart types

+

Visualise your data in different ways. Each of them animated, fully customisable and look great, even on retina displays.

+
+
+ +

HTML5 Based

+

Chart.js uses the HTML5 canvas element. It supports all modern browsers, and polyfills provide support for IE7/8.

+
+
+ +

Simple and flexible

+

Chart.js is dependency free, lightweight (4.5k when minified and gzipped) and offers loads of customisation options.

+
+
