Answer:
The circle graph or pie chart
Explanation:
The pie chart is a very efficient visualization tool capable of adequately transmitting the details of a distribution by breaking it down into groups. Each groups takes up a certain fraction of the circle based on the percentage. Depending on the tweaking, each segment of the circle may be given different colors with the percentage taken up by each segment displayed in them or many other features added. The entire circle represents the whole distribution, with each segment thus used to mean the different groups or categories.
