I'm embedding my proof of concept that I made with the new Visifire Silverlight Charts. I realize the animations are flashy but useless. That's OK, I'll eventually stumble upon "sexy" and "useful" when it comes to data visualizations (Good Heavens, I'm a Nerd!)
BTW, those guys at Visifire are awesome. I posted a question on the forum and within a half hour I got a response.
