• Displays data in vertical bars.
• Useful for comparing values across categories.

Detailed Explanation

Column charts are a type of graphical representation that uses vertical bars to show data. Each bar represents a different category or group of data, with the height of the bar indicating the value or amount of that category. This makes it easy to quickly see how different categories compare against each other. For example, in a chart showing sales figures for different products, each product could be represented by a bar, allowing you to see which product sold the most just by looking at the heights of the bars.

Examples & Analogies

Imagine you have a school science fair where each student has a project. If we want to see which project got the most votes, we could represent each project as a vertical bar. The taller the bar, the more votes it received, making it easy to visualize the winner without having to tally numbers.
