What is a bar graph that shows the frequency of data?

A bar graph that shows the frequency of data is a visual representation used to display the number of occurrences of different categories or groups within a dataset. Each bar represents a category, with the height or length of the bar indicating the frequency or count of data points in that category. This type of graph allows for easy comparison between different categories and helps identify trends or patterns within the data. Bar graphs can be oriented vertically or horizontally, depending on the preference of the presenter.
