[I] MapBox chart doesn't let you properly use a numerical column for the Point Radius field [superset]
msyavuz opened a new issue, #34398:
URL: https://github.com/apache/superset/issues/34398
### Bug description
If you try to select a numerical column for the Point Radius field other than the default Auto value, the chart doesn’t display anything.
How to reproduce the bug
1. Create a MapBox with the sample GeoData dataset
2. Drag and drop the LON and LAT columns to the respective fields
3. Go to the Point Radius field and select the radius_miles column
4. Select miles in the Point Radius Unit field
5. Click on Update Chart
### Expected results
You see your chart shows the points according to the numerical values of the radius_miles column
### Actual results
The chart doesn’t display any value, just an empty map.

<!-- Answer -->
This is a confirmed bug in the current Superset master: when you select a numerical column for the MapBox chart's Point Radius field, the frontend passes the column name as a string instead of a number, which breaks the rendering logic and results in an empty map. The backend does include the correct per-point radius in the geoJSON, but the frontend expects a numeric fallback and mishandles the string value, causing the issue. No recent pull requests have addressed this bug as of July 2025, and it's not documented as a known limitation or fixed in recent updates [[source]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/legacy-plugin-chart-map-box/src/transformProps.js).
As a workaround, make sure your radius column contains only valid numeric values and, if your data source uses NUMERIC/DECIMAL types, try casting the column to BIGINT in your SQL query to avoid type conversion issues that can cause rendering problems in Superset charts [[source]](https://github.com/apache/superset/issues/33174). If the problem persists, it will likely require a code fix to ensure the frontend always passes a valid numeric fallback for pointRadius.

Hi! I would like to work on this through the Preset bounty program if the bounty is active. I have reviewed the bug report and can investigate the Point Radius numeric handling on the frontend. If this is available, I am happy to open a PR.
