Radar Chart

Radar Charts are an effective type of data visualization for comparative analysis. Each variable is represented on axes. All axes use one scale and are arranged radially within the same distance from each other. The series is shown as a line that forms a closed polygonal chain by connecting data points on axes, and in this way it displays the value of the phenomenon in question in a given category.

Radar Charts make it possible to compare values both to each other within a single data set (single-series chart) and in a certain category across several or many data sets (multi-series chart). When using the Radar Chart type, it is important to remember the following:
  1. reading a chart with a large amount of series can be complicated,
  2. there should be at least three axes, while too many axes can make a chart illegible.
