Polar chart

A polar chart is a circular chart in which all sectors have the same angle, but different size. Using multiple small polar plots is a good solution to depict similarity or differences.

To create a polar chart you must select circle chart in mark type, and polar chart in chart type.

The quantitative variable should be linked to size, and the categorical variable that determines how many different sectors the chart will have should be linked to “Subdivision” or to “Color”.
