It enables you to present data in a visually compelling way, making it easier to understand regional variations, identify patterns, and communicate insights. The Map Chart in Excel is particularly useful for displaying data that has a geographic context, such as sales performance by region, population density, or any other data that can be associated with specific locations. It provides a visual representation of the data that helps reveal geographical patterns, identify trends, and compare values across regions.
