== ruby-googlechart
== DESCRIPTION
ruby-googlechart is a ruby library which provides object-oriented
access to the Google Charts API.
This library has largely been done as an exercise. These other ruby
libraries are more mature and may be better suited to your needs:
== FEATURES
- Line charts (line, XY, sparkline)
- Bar charts (horizontal, vertical, grouped, stacked)
== SYNOPSIS
require 'google_chart'
url = GoogleChart.Line(:data => [1, nil, 2, 8, 1])

url = GoogleChart.Bar do |c|
c.axes = {:x => %w[Q1 Q2 Q3 Q4], :y => 0..400}
c.data = [335, 285, 240, 220, 160, 175, 200, 205]
