London is a great place for tourists, and people often talk about the "hottest" places in London. I wanted to build some way to visualise this, and I'm really happy with the results.

By mining the 4square api I was able to determine where people were within London, places like coffee shops, tourist attractions, clubs and gig venues are all unified into 4square. By getting a map from Open Street Map and overlaying the data from 4square using a simple lighting equation I got really nice results. 

Check the map out here and the source on github feel free to fork me :)
