Radar Chart

Radar chart is a two-dimensional chart type designed to plot one or more series of values over multiple common quantitative variables. Each variable has its own axis, all axis are joint in the center of the figure. Radar chart is often criticized in dataviz, and it is probably not the best way to convey information.
