What type of graph uses horizontal bars to show different values?

A bar graph is designed specifically to display different values using horizontal bars, making it easy to compare discrete categories of data visually. Each bar's length or height corresponds to the value it represents, allowing for quick interpretation and analysis of the data presented.

In contrast, a pie chart displays data as slices of a circular pie, which represents parts of a whole rather than comparing individual values across categories. A line graph shows trends over time or continuous data points, connecting data points with a line, which is different from the categorical comparison used in bar graphs. A histogram resembles a bar graph but is used to display the frequency distribution of continuous data, where the bars touch each other, indicating the continuous nature of the data rather than discrete categories.
