Release Name: 0.3.0

Notes:
== PROBLEMS/TODO

* Add support fills (area or background), grid lines, shape markers, range markers 
* Support shorthand colors and color names
* Make venn data specification friendlier

There are lots of missing features. Until they're implemented, you can directly specify
query parameters using the :extras key, e.g.,

  # provides a legend for each data set
  g = GChart.line(:data => [[1, 2], [3, 4]], :extras => { "chdl" => ["First", "Second"] })


Changes:
== 0.3.0 (2007-12-24)
  
  * Breaking change: labels --> legend
  * Switched to RSpec, added skeletal specs for all types
  * Extensive refactoring, pulled chart types into GChart::Base subclasses
  * (bug) Errors in the static helpers should report a reasonable file and line

== 0.2.0 (2007-12-12)
