The first thing I noticed about this is that it feels slow. If you want people to use it, navigating around the map needs to feel smooth. This could be something as simple as putting in a little delay between the user moving the map and you starting to load your pricing data. The second thing I noticed is that it was, by default, zoomed in somewhere in Germany. I am not in Germany. Why not centre it based on the user's IP? Or, just have it zoomed out to start with? I like the idea though.
