CSS Graphs Helper for Ruby on Rails
Description
A Ruby on Rails helper for making simple graphs. The graphs use only CSS/HTML (and an optional gradient image).
Vertical bar graphs, horizontal bar graphs, and complex bar graphs with an image marker.
Inspiration thanks to Apples to Oranges.

Issue this command inside your Rails app:
./script/plugin install http://topfunky.net/svn/plugins/css_graphs
It automatically installs itself into the default Rails helpers, so you don’t have to!
You can also copy the graphics to your images directory with the generator:
# No arguments are needed ./script/generate css_graphs
Sample
Usage
In your view:
<%= bar_graph [['Gouda', 24],
['Havarti', 9],
['Provolone', 81],
['Wensleydale', 57],
['Stilton', 42]] %>
NOTE: Earlier versions took a splatted array. It now takes a single array of arrays.
Limitations of the First Release
- Only one graph can be used per page.
- Values must be in the range 0-100.
