Silverlight Charting Component

I just found a Silverlight charting component suite called Visifire. It is open source and is licensed under GPL. From the demo video below, it really get me excited, it supports most of the common chart types we need - bar, line, area, pie, stacked bar, and combination of chart types in one chart.



I haven't play it in Visual Studio, but by the look of the online Chart Designer at Visifire website, I guess most of the features are already exposed through properties, so it should be quite easy to use.
