Morris.js - pretty time-series line graphs

Morris.js is the library that powers the graphs on http://howmanyleft.co.uk/. It's a very simple API for drawing line, bar, area and donut charts.

Cheers!

Requirements

• jQuery (>= 1.7 recommended, but it'll probably work with older versions)
• Raphael.js (>= 2.0)

Usage

See the website.

Development

Very daring.

Fork, hack, possibly even add some tests, then send a pull request :)

Developer quick-start

You'll need node.js. I recommend using nvm for installing node in development environments.

With node installed, install grunt using npm install -g grunt, and then the rest of the test/build dependencies with npm install in the morris.js project folder.

Once you're all set up, you can compile, minify and run the tests using grunt.
