Convex Polygons and Radar Charts
Abstract
The graph shown above, which often appears in score reports from mock exams or sports tests, is called a radar chart . It visually highlights which subjects a student excels in and which ones need improvement. The shape of the figure also gives an intuitive sense of how balanced the overall performance is, and the area can suggest the total score at a glance. It seems like a great way to present information—but is it really all good?
