Radar Chart helps to compare multiple quantitative variables
A Radar chart, a.k.a. Spider Chart or a Kiviat Chart, is a 2D chart of three or more quantitative variables that are represented on axes beginning from the same point. Every axis is a quantity for a different category value for the subject.
Anyway, the relative position of the series gives the possibility to see data relationships and compare them based on multiple categories.
The radar chart is helpful when you want to see which variables have similar values or if there are any exceptions among each variable.
Every variable has an axis starting from the center. All axes are organized radially, with equal distances between each other.
