Answer: A circular chart can be used to illustrate data in following examples:
1) To show the percentage distribution of religions in a country.
2) To show the quantity of different foods produced in a country in a given year.
3) To show the number of seats won by different political parties in a single election.
Explanation: In order to illustrate data using a circular chart, it is mandatory that the data be comparative in nature. The data illustrated using a circular chart broadly dispenses the picture of the margins of difference between the figures.
Bigger figures acquire more space in the chart giving out an idea of the disproportion that exists among the figures and the dominance of the bigger figures.
