Bubble style

A bubble map shows different sized circular markers for points, lines, and polygon features. The bubble sizes are based on a selected numerical attribute value from your layer.

To style your data as a bubble map, open the Layers panel, and click the edit icon for your desired layer.

Navigate to the Style tab, and select Bubble from the map style chooser.
