URL: https://github.com/apache/superset/pull/38458#issuecomment-4040746206
## **Sequence Diagram**
This PR updates the MapBox ScatterPlotGlowOverlay so cluster circle radii
are remapped to stay between a minimum ratio of the base radius and the full
radius, ensuring clusters are never smaller than individual points and that
zero or negative labels yield valid, visible circles.
