Which type of chart is designed to display multiple bar charts together?

A side-by-side bar chart, also known as a grouped bar chart, is specifically designed to display multiple categories of data together for comparison. This chart allows one to visualize two or more datasets side by side for each category, making it easy to compare the values of different groups across the same categorical variable.

With this format, each group of bars corresponds to a category, and each bar within that group represents a different dataset. This clarity aids in understanding the relationships and differences between the datasets being analyzed, which is essential when presenting complex information.

The other chart types mentioned serve different purposes. A vertical bar chart displays data vertically but doesn't necessarily compare multiple datasets next to one another in a grouped manner. A stacked bar chart shows multiple data series stacked on top of each other within a single bar for each category, which can make it difficult to compare individual data points directly. Lastly, a pie chart is used to display parts of a whole and does not accommodate multiple datasets in the same way side-by-side bar charts do, making it unsuitable for comparisons across categories.
