Marie Woltman is a Power BI guru whose maps we often reference on our courses. In this blog she explains why MapBox is her preferred mapping tool, and shows how to use it to create custom styles and layers.

You need a minimum screen resolution of about 700 pixels width to see our blogs. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
Conclusion and examples of Mapbox maps
Once you've mastered the steps to setting it up, the Mapbox visual offers a huge amount of functionality. It gives you complete control on stylising your background map data and allows you to display multiple custom layers and datasets which most other map visuals can't do. It also enables you to show up to the maximum possible 30,000 data points (and fast). Plus, it works for Publish to Web! What more can you ask for in a Power BI map visual?! It's just awesome in my opinion.
I thought it would be useful to end with some examples of Mapbox maps that I've created!
Pilot flight log
This pilot flight log combines satellite and contour mapping layers. Also note the use of another map visual, the route map (hover over the table or use table drillthrough to display a large route map).
Two maps in one!
House price data
This map shows various different map displays, giving the option to switch the display between Circle, Cluster and Heatmap.
Here I've chosen to show the heat map, but am about to switch to a cluster map.
The second page gives an example of a choropleth (filled map):
Here I'm selecting the East Midlands region.
Road accident statistics
The road accident statistics maps (much alluded to on Wise Owl courses, I gather) shows the nature of road accidents in any area and timeframe:
Here I'm showing accident data for Stockport.
The A & B Road Route Performance map shows a good example of the use of data points and polygons:
This is showing the A386 in central Bideford.
You can see all these maps and more at my website, which also explains how to contact me should you want help in uncovering data insights visually!
