In a CD collection program, I have each artist's country of origin stored in the main database and want to display a map of the world which:

1. Colour-codes each country depending on the number of CDs by artists in that country
2. Allows clicking on each country to filter a list of CDs to only ones by artists in that country

This is a heavily simplified version of what I'm trying to do, but if I can at least get this far the rest should be easy enough to figure out. So far the closest thing I've found to what I'm trying to do is here:

Ideally I don't want to be embedding Flash in my program though, and the only other solutions I've found all involve SVG which I haven't managed to get working in practice outside of a web browser control (and I DEFINITELY don't want to be embedding a browser in the forms). Something in pure managed code and either GDI+ or WPF would be preferable. Are there any existing components that would get me started, or can anyone suggest how to approach it from scratch?
