This is also a 2D chart drawn as multiple sectors in a circle. This chart is useful when we want to highlight the relative importance of all the data points.
Let's take a look at the example chart that is drawn with the same dataset as before to understand it better:
As you can see, it's easy to understand the relative importance of the amounts owned by each of the persons using this chart.
The conclusions that are drawn are similar to the previous charts. But the graph is a simple circle and there are no multiple dimensions here to burden the user.
