Which of the following best describes the purpose of using bar graphs in economic data representation?

Bar graphs are useful tools for showing economic data because they make it easy to compare different categories. Each bar represents a specific group, like sales in different years or profits from various products. By looking at the height of the bars, you can quickly see which categories are larger or smaller, helping you understand trends and patterns. For example, if you have a bar graph showing the sales of three different toys over a year, you can instantly tell which toy sold the most just by comparing the lengths of the bars. This visual representation simplifies complex data, making it more accessible for everyone to understand.
