A circle graph, also known as a pie chart, effectively illustrates the percentages of a whole by representing different categories as proportional slices of a circle. Each slice reflects not only the size of the category in relation to the whole, but also visually emphasizes how much one category contributes to the overall total. This visual representation allows for easy comparison between the parts and the whole, making it clear how individual components relate to the overall dataset.

Circle graphs are particularly useful when dealing with categorical data where it's important to see the proportion of each category in relation to the total. For example, if you were to depict the distribution of student enrollment by major in a college, each major could be represented as a slice of the pie, giving a clear view of each major's share of the total student population.

Other options, although pertinent to data representation, do not accurately capture the primary purpose of a circle graph. Options addressing overall amounts or measurements of area delve into different concepts, while trends over time are best represented through line graphs or bar charts, which emphasize changes and movements over a given period.
