[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.
