I like these geographical data visualizations but I'm always slightly disappointed when the data turns out to be 90% what you would expect. I always think it might be more interesting to show some slightly more nuanced data if possible, like instead of showing volume of stuff, show the rate of growth of stuff or where stuff has appeared for the first time.
