Those graphs are called Radar Charts.
The radar chart is a chart that consists of a sequence of equi-angular spokes, called radii, with each spoke representing one of the variables. The radar chart, also known as a spider chart or a star chart because of its appearance, has its zero starting point in the middle. From the middle, each axis of the chart can protrude out like the spokes on a wheel. There can be one axis for each subject, and there is no limit on the number of subjects that can be used. It can also be described as a radial grid with the zero starting point being the middle.
Importance of Radar Chart :
Assume that somebody asked you to analyze and compare the production and profit details of three companies (Let Company A, Company B and Company C). Usually people tend to draw bar charts or tables. So assume that you plotted a traditional bar chart for the above purpose. Now you have to observe each cluster of bars separately. But when there are a large number of variables, the bar Chart might look cluttered. It is kind of difficult task for you to analyze the given bar charts.
In such scenarios, try the Radar Chart instead. The radar chart is not as cluttered as the bar chart, making it more appealing to the reader. The connected pattern of the radar chart allows the reader to see the relative position of Company A to Company B and Company C quicker than with the bar chart, whether the reader is examining the attributes independently or collectively.

When to use Radar Chart ?
- If you can’t accommodate different quantitative scales in a bar graph
- If the objective if to compare symmetry rather than magnitudes
Advantages of Radar Chart :
- It is used for a quick visual interpretation of data from various sources.
- The radar chart is not as cluttered as the bar chart.
- It is not designed to be used for identifying the accuracy in data, but rather generalized relationships between data.
Now let's have a look at an example :
Assume that you have the marks details of 9 students from Two schools (School 1 and School 2). The tabular representation of the data will be,
