A pie chart is a circular graph that shows how a whole is split into categories. Each sector represents a category, and the size of the sector is proportional to that category's share of the total.
A pie chart works best when you want to ask “how much of the whole belongs to each group?” The whole circle stands for 100%, and each slice shows one part of that whole.
