The visualization is titled Documentation blueprint. Big box = class; edge = inheritance link; small box = method; small box height = number of lines of code; small box width = number of collaborating classes; red border = non commented; green border = test

This visualization is obtained from Mondrian. Yeah, Mondrian is pretty poorly documented. I will work on it.

Feedback wanted
