Use HTML5 charts and the canvas tag to build faster websites

RGraph is a HTML5 canvas based JavaScript library built for web charts and supports over twenty different types of visualisation. Using the <canvas> tag, RGraph creates these charts inside the web browser using JavaScript, meaning quicker pages and less web server load. This leads to smaller page sizes, lower costs and faster websites.

Open Source and Free to use!

Open Source - MIT icense RGraph is truly Open and Free to use for any purpose under the MIT license. The full source is included in the download and you can edit it as you need.

Forget Flash or Silverlight - JavaScript and the canvas tag are built in to all modern browsers and allow for quick and easy 2D drawing. Using RGraph to produce your charts makes the process a breeze and enables you to quickly get up and running. The Canvas tag is supported by all modern browsers and mobile devices meaning your charts and graphs will be seen by the widest possible number of users.
