Charter School Graph Plot

http://blogs.edweek.org/teachers/living-in-dialogue/hassard3.jpg

This is an interesting graph comparing public and charter schools based on their minority student population and their SAT scores. To be honest, the design of the graph isn't terrible. The goal of the graph seems to be giving the audience an overall impression of the disparity between predominantly Caucasian and predominantly minority schools. I do have two issues with the graph, however.

Color Conventions

This is an example of a color convention that doesn't make any sense to us...it is unrecognizable and confusing to interpret because of the distortion of how we usually see that color. This image seems to exist merely to test our reliability upon these conventions, because there is no other type of function this image could serve.
