What type of chart would you typically use to show parts of a whole?

A pie chart is specifically designed to illustrate the proportions of different parts that contribute to a whole. Each "slice" of the pie represents a category's contribution relative to the total, making it immediately clear how each part compares to the entire dataset. This visualization is particularly effective when you want to communicate how distinct parts relate to one another in terms of their share of the total.

In contrast, line charts are better suited for showing trends over time, bar charts are typically used to compare quantities across different categories rather than showing proportions, and scatter plots are ideal for displaying the relationship between two variables rather than illustrating parts of a whole. Thus, the pie chart is the most appropriate choice for conveying the concept of parts of a whole.
