Azure Map Visual - No cluster bubble count number other than circle. Loss of relative size for squar

Hi,

This is expected behavior and a current limitation of the Azure Maps visual in Power BI, not something you’re doing wrong.

The cluster count label is only rendered for the Circle marker shape. When you switch the marker type to Square, Icon, or other shapes, Power BI does not render the cluster count text, and you also lose the visual size context that circles provide.

Why this happens

• Cluster labels are part of the built-in circle cluster renderer

• Non-circle shapes are treated as symbol layers, which don’t support text overlays for cluster counts

• The visual doesn’t currently expose any option to:

  • Enable labels for non-circle shapes

  • Customize cluster label behavior per marker type

So when you toggle from Circle → Square/Icon, the clustering still happens, but:

• The count label disappears

• The visual cue for relative cluster size is lost

Is there a workaround?

Unfortunately, no supported workaround inside the Azure Maps visual today.

Your options are:

• Stick with Circle markers if cluster counts are required

• Or disable clustering and rely on individual markers

• Or build a custom visual (or use a different map visual) if labeled clusters with non-circle shapes are a hard requirement
