Awesome. Just when I was finishing my D3 visualizations. Trying not to get too distracted... ;)<p>Any chance you could publish the heat map you had in the first demo? I'd love to get a head start in integrating 2D layers to this. Even if it were some less than functional code.<p>I presume OpenStreetMap sends map data as vectors, so it should not be too difficult to replace that with other geo sources. I immediately see a dozen use cases even with relatively static data.<p>Thank you :)
