Which graph type is best suited for comparing categories?

A bar graph is best suited for comparing categories because it uses rectangular bars to represent the values of different categories, allowing for an easy visual comparison between them. The lengths or heights of the bars correspond to the numerical values for each category, making it straightforward to identify which categories are larger or smaller in value. This visual representation highlights differences and similarities in a way that is easily interpretable at a glance.

In contrast, a line graph primarily displays trends over time, making it ideal for showing changes within a single category rather than comparing multiple categories. A pyramid chart is typically used to show hierarchical data, such as population distribution, and does not effectively compare distinct categories in isolation. A scatter plot displays relationships between two continuous variables and is not suitable for handling categorical data comparison directly, as it focuses on correlation rather than differences among distinct categories.
