It is most effective when you want to view several different factors related to one area in one holistic view.
In a radar chart, the value of the data point starts from the center of the chart. A point close to the center on any axis represents the minimum value and a point near the edge represent the maximum value. 
 
The following are the most common use case for using this chart.

2. From the Dimensions pane, select Athlete.
3. From the Measures pane, select Total Medals.
4. Click the Image Modified tab and then clickImage Modified. Visualization builds a Radar Chart.
