The radar chart is a chart and/or graphic that consists of a succession of equi-angular spokes, termed radii, with each spoke indicating one of the variables. The data length of a spoke is proportional to the magnitude of the variable for the data point relative to the maximum magnitude of the variable across all data points. The data values for each spoke are connected by a line. This gives the plot a star-like look and is the source of one of the plot's most recognized titles.
