Power BI Custom Visuals Class (Module 59 – Drilldown Cartogram)

In this module you will learn how to use the Drilldown Cartogram Custom Visual.  The Drilldown Cartogram is a map visual that displays a circle for each location with varying size and color based on specific values you provide.

Module 59 – Drilldown Cartogram


Key Takeaways

  • Displays a circle for each location with the size and color based on the values you specify.
  • Allows you to drill down through your hierarchy data.
  • You must add a shape file yourself to use this visual.


This Drilldown Cartogram map shows military veterans by county in the United States.

  • Under the Format paintbrush there are several sections available to modify the appearance.
  • Under the Data colors section you can adjust the type of colors used on the map and the thresholds that determine their color.


  • The Shape properties should really be your first stop when working with this visual. Without configuring at least the Level 1 property with a shape file you will see nothing on your map. You can also change the type of map projection is used here.


  • Under the Default color section you can control things like the color of the border between shapes and how thick the lines are.


  • The Circle settings allows you to control the size of the circles of the map and the border thickness around each circle as well.


  • Using the Zoom properties you can change the behavior of the visual when you zoom into a selection you’ve made or manually zooming on your own.


  • Turning on/off the Collision property will control the “bounce” you may notice when the circles touch each other on the map.


In addition to these properties you have a set of settings that appears on every visual to adjust the background color, add a border around the visual and lock the aspect ratio.
