Open Flash Chart

Finally got around to implementing Shapes and shape_point in the Open Flash Chart Python library. You can now finally draw polygons on to the charts! It didn't take too long to implement which was good. I did get stuck on writing the demo though. I couldn't follow my use of arrays in my code and I had a "null" value problem in the JSON ><. I've now updated the code.google.com page for the library with a new uploaded zip file of the library and a new Wiki page for the change log.
