In the time since posting my last collection of Silverlight/WPF Charting links, there's been some great activity! Of particular significance, the June 2009 WPF Toolkit includes the same Data Visualization goodness that was introduced for Silverlight and the July 2009 release of the Silverlight Toolkit added a TreeMap control. Without further ado, here are the latest links (FYI: previously published links are gray):

Overviews (100 level)

Scenarios (200 level)

Internals (300 level)

Team Member posts (Partner level)

My posts (Ego level)

Many, many thanks to everyone who's spent time helping others learn how to use Silverlight/WPF Data Visualization!

PS - If I've missed any good resources, please leave a comment with a link - I'm always happy to find more good stuff! :)
