Bar Chart

Definition

A bar chart is a graphical representation of data that uses rectangular bars to show the frequency or count of data points in different categories. Each category is represented by a separate bar, and the height of each bar corresponds to the value it represents.

Analogy

Imagine you have a candy store with different types of candies. To visually represent the popularity of each candy, you could create a bar chart where each candy type is represented by a separate bar. The height of each bar would correspond to the number of times that particular candy was purchased, giving you an idea of which candies are more popular than others.
