Creating Geographic Maps in Power BI: Visualization Techniques

Join My PowerBI Group.

Creating geographic maps in Power BI is a powerful method to visualize data with a spatial component, such as sales by region, customer locations, or resource distribution. 

Here are some techniques for creating geographic maps in Power BI:

Basic Map Visualization: Begin by adding a map visualization to your Power BI report canvas. Drag and drop the geographic field (e.g., country, state, city) from your dataset onto the map to plot the data points.

Choropleth Maps: These maps utilize shading or color gradients to depict the magnitude of a variable across geographic regions. In Power BI, create a choropleth map using the filled map visualization and assign a numerical field to the "Values" or "Color saturation" property. Customize the color scale and legend for clear data communication.

Bubble Maps: Bubble maps use bubbles of varying sizes or colors to represent different values at specific locations. Create a bubble map in Power BI with the bubble map visualization, assigning numerical fields to the "Latitude," "Longitude," and "Size" properties. Adjust the bubbles' color, size, and transparency to convey information.

Heat Maps: Heat maps show data density with color gradients indicating the intensity of data points in various areas. Create a heat map in Power BI using the filled map visualization, assigning a numerical field to the "Color saturation" property. Modify the color gradient and opacity to visualize data density effectively.

Shape Maps: Shape maps use custom shapes or images to depict geographic regions. Create a shape map in Power BI with the shape map visualization by importing custom shapefiles or SVG images representing your geographic areas of interest.
