Just messing around with d3.js's sweet graphs.
git clone https://github.com/mybuddymichael/graphs.git
cd graphs
bundle install
guard
open index.html
The Guardfile will compile LESS and CoffeeScript, along with triggering Livereload.
If you're using pow, also do this:
cd ~/.pow
mkdir graphs
ln -s <path/to/graphs> graphs/public
And then visit graphs.dev.
