Just grazing around the world of map visualisations. I thought this site http://www.viewsoftheworld.net/?p=736#more-736 really brought home the dangers of visualising data on regular maps. In particular I really like this hexmap that shows the truer impact of the data while still giving enough positional information for the reader to see geographic locations and trends. Great stuff. Now to see if I can get an SVG version :).
