"""
[RadarChart] - General purpose node for Radar Charts
A radar chart is a graphical method of displaying multivariate data in the form
of a two-dimensional chart of three or more quantitative variables represented on axes
starting from the same point. The relative position and angle of the axes is typically
uninformative, but various heuristics, such as algorithms that plot data as the maximal
total area, can be applied to sort the variables (axes) into relative positions that reveal
distinct correlations, trade-offs, and a multitude of other comparative measures.

A radar chart is a graphical method of displaying multivariate data in the form
of a two-dimensional chart of three or more quantitative variables represented on axes
starting from the same point. The relative position and angle of the axes is typically
uninformative, but various heuristics, such as algorithms that plot data as the maximal
total area, can be applied to sort the variables (axes) into relative positions that reveal
distinct correlations, trade-offs, and a multitude of other comparative measures."
