Which type of visualization is typically used to represent geographic data in Power BI?

The map visualization is specifically designed for representing geographic data within Power BI. This type of visualization enables users to visually display data points on a geographic map, leveraging geographic coordinates such as latitude and longitude, or geographical groupings like countries, states, or cities. Maps effectively illustrate how data varies across different locations, making it easier to identify trends, patterns, and insights that are location-based.

In contrast, bar charts, pie charts, and line charts are typically used for categorical or time-series data rather than geographic data. These visualizations focus on comparing values, showing proportions, or displaying trends over time, which is not the primary purpose when it comes to mapping data geographically. Hence, map visualization stands as the most suitable choice for geographic representation in Power BI.
