This chart does not seem to be a measure of school performance by district, but of towns where the student resides. See the note buried at the bottom:

"Based on residence, not school location"

So is the point to see if there is a correlation between where the student lives, and their academic performance, or what school they attend, and their academic performance. Sounds like some basic factor analysis should be done.

The colours are presumably the boroughs shown on the left hand side.

Nice one. The chart becomes even better if we add some bars and text to the dots: https://plus.google.com/photos/104692213800963690780/albums/5678218374538559185/5678218373472116706
