I've been meaning to blog about this for some time...better late than never, I say:
So, when I first looked at WPF (then Avalon) back in early 2005 we had just had another presidential election, so based on current events I created a sample. Basically, I converted individual SVG maps to Avalon polygons and carefully arranged them by hand and did the data binding.
Really cool app that uses SVG as the basis for a WPF app, and uses WPF databinding to apply styles to WPF polygons to create a US map for analyzing election results. Neat application of the technology. Justin's made the source available, so take a look.
