π Topic Summary
A circle graph, also known as a pie chart, is a circular chart divided into sectors, each representing a proportion of the whole. The entire circle represents 100%, and each sector shows the percentage of a particular category. Understanding circle graphs helps us quickly compare different parts of a whole. Think of it like slicing a pizza β each slice is a piece of the whole pizza!
To interpret a circle graph, pay attention to the size of each section and the labels that tell you what each section represents. Larger sections mean a larger proportion. Let's practice!
