What type of chart is used to show a distribution of data points or perform a comparison of metric values across different subgroups?

A bar chart is an effective tool for showing the distribution of data points or comparing metric values across different subgroups. This type of chart visualizes data using rectangular bars, where the length or height of each bar corresponds to the value it represents. By aligning bars side by side, it allows for easy comparison among various categories, making it simple to see which subgroup has the highest or lowest metric value.

Bar charts are particularly useful when the data consists of discrete categories or groups, as they provide a clear visual representation that can highlight variations in those groups. Their straightforward format facilitates quick insights into the data, enabling stakeholders to make informed decisions based on the comparative analysis.
