Which type of graph is used to distinguish between different percentages?

A pie graph is specifically designed to display information in a way that highlights the proportions of different categories as parts of a whole. This type of graph divides a circle into sectors, where each sector represents a percentage of the total. Each portion of the pie visually conveys how much each category contributes to the overall total, making it easy to understand the relative sizes of the parts compared to the whole.

Pie graphs are particularly effective for illustrating limited data sets where the focus is on the percentage distribution among a few categories. The visual representation allows for quick comparisons of those percentages, which is essential when the goal is to convey differences in proportions clearly and succinctly.

In contrast, while bar graphs and column graphs can also convey categorical information, they do so more effectively in terms of comparing absolute values rather than specific percentages. Line graphs, on the other hand, are best suited for showing trends over time rather than comparing parts of a whole. Thus, when the need arises to showcase different percentages clearly, the pie graph stands out as the most suitable choice.
