Morris.js is a lightweight library that uses jQuery and Raphaël to make drawing time-series graphs easy. Morris.js started life as the code that powered the graphs on howmanyleft.co.uk. Now it’s been open-sourced for the whole world to extend and enjoy.

It has been tested on IE6+, Safari/Chrome/Firefox, iOS 3+ and Android 3+. The public API is terribly simple. It’s just one function: Morris.Line(options), where options is an object containing many configuration options. And it is licensed under BSD License.

Requirements: jQuery and Raphaël Framework
