Bar graphs are primarily used to represent quantities of different categories. This is because each bar in the graph corresponds to a specific category, with the height or length of the bar indicating the quantity associated with that category. For instance, a bar graph might display the number of students enrolled in various subjects, where each subject represents a different category. The clear visual separation of bars makes it easy to compare the quantities across the various categories quickly.

While other types of graphs, such as line graphs, are better suited for showing trends over time or the magnitude of change, bar graphs excel in comparing distinct, non-continuous groups. This makes them a valuable tool for visualizing categorical data, enabling viewers to grasp differences in size or amount at a glance.
