Which type of chart is primarily used to show how each category contributes to a whole?

Pie charts are used when you want to show how parts add up to a whole. The circle is divided into slices, and the size of each slice reflects that category’s share of the total. This makes it easy to compare portions and see which categories dominate the whole at a glance. Histograms show how often values occur within data ranges, not how a total is built. Line graphs reveal changes over time. Bar charts compare amounts across categories but don’t inherently emphasize a total that the parts sum to. Since the goal is to visualize each category’s contribution to the whole, the pie chart is the best choice.
