Which chart type is used to show values for geographic regions?

The Choropleth Map is specifically designed to represent values for geographic regions by using different colors or shades to display variations in data across a specific area. This chart type allows for a clear visual comparison of values or metrics at a glance, such as population density, income levels, or election results across different regions. By utilizing a geographic map as a base, it effectively communicates the spatial distribution of the data, making it easy to identify trends and outliers based on geographic locations.

In contrast, while other options may display data effectively, they do not focus on geographic regions in the same way. For example, a Cluster Map shows the density of occurrences in specific areas without necessarily depicting values tied to specific regions. A Grid Plot represents data in a matrix format, which is useful for comparing relationships between variables but lacks geographic context. A Statistics Table organizes data in a tabular format, which is great for detailed analysis but does not provide an immediate visual interpretation of geographic information. This is why the Choropleth Map is the most appropriate choice for visualizing values tied to geographic regions.
