Open source charting library for Silverlight 2..
Visifire has a free, open-source library for 2D and “3D looking” charts built using Silverlight 2.. Very cool!!
For me, this is obviously handy when creating demos and showing Silverlight capabilities; for commercial use they also have a commercial license..
Emailing them to see if they would be interesting on working with us for their charts to be styled in Blend; in the mean time enjoy the charts and play with them..
