drawr
    by Aaron Patterson
    http://seattlerb.org/

== DESCRIPTION:
  
This is a ruby wrapper around Plotr with a similar API to Gruff.  You can
create graphs with a similar interface to Gruff, but offload the rendering
to the browser!

== FEATURES/PROBLEMS:
  
* Needs more tests!

== SYNOPSIS:

An example in rails.  Your controller:

  class GraphController < ApplicationController
    def index
      @drawr = Drawr::Pie.new
      @drawr.title = "Twan"
      @drawr.data("One", [1])
      @drawr.data('Two', [2])
      @drawr.data('Three', [2])
      @drawr.data('Four', [10])
      @drawr.data('Five', [6])
    end
  end

Your view:

  <html>
    <head>
      <%= javascript_include_tag 'prototype' %>
      <%= javascript_include_tag 'excanvas' %>
      <%= javascript_include_tag 'Plotr' %>
    </head>
    <body>
      <%= @drawr %>
    </body>
  </html>
