That was my first thought. But judging from the graphic I think this is a milkshake-specific crazy game.
In pursuit of a correlation between three specific business segments I mapped two other specific business segments in an attempt to determine the degree of decorrelation. The idea being: all businesses will have a certain amount of demographic correlation simply because of population centers and roads. By demonstrating a counter-model I can establish (somewhat) that the correlation I have found between the three business segments I give a shit about is not a fluke. The businesses I give a shit are all within the yellow globs. This is a win. The businesses I don't give a shit are not. This is also a win.
