To visualize data over a geographical area, which Tableau mapping feature can be used?

When visualizing data over a geographical area in Tableau, all the mentioned mapping features—Heat Maps, Bubble Maps, and Filled Maps—are effective tools depending on the specific needs of the analysis.

Heat Maps allow users to represent data density across a geographical area by varying color intensity. This is particularly useful for identifying hotspots or areas with high concentrations of events or occurrences.

Bubble Maps use circles to represent data points on a map, with the size of the circle indicating the magnitude of the data for that location. This is beneficial when you want to compare relative values across different geographic locations while also providing a clear visual of where these data points are situated geographically.

Filled Maps, also known as choropleth maps, color regions based on a specific measure, allowing for easy comparisons between different areas. This is particularly useful for visualizing aggregated data such as population distribution, average income, or any metric that can be represented as a region's value.

Since each of these features caters to different visualization needs and preferences, they collectively provide versatile options for effectively visualizing geographical data in Tableau. Therefore, the answer that encompasses all these mapping features is the most comprehensive one.
