Radar charts
Radar charts compare multiple quantitative variables and are useful for visualizing which
variables have similar values, or if outliers exist among the variables. Radar charts consists of a
sequence of spokes, with each spoke representing a single variable. Radar Charts are also useful for
determining which variables are scoring high or low within a data set.
Creating a simple radar chart
