<!-- Answer --> I found a similar unsolved discussion that might be relevant to your issue: [Insert a Multipolygon into a Deck.gl Polygon chart](https://github.com/apache/superset/discussions/31405), which was last updated on December 11, 2024 <sup>[[1]](https://github.com/apache/superset/discussions/31405)</sup>. For your specific issue with multipolygon visibility in Superset, here are a few steps you can take to troubleshoot: 1. **Check GeoJSON Format**: Ensure that the GeoJSON for the multipolygon is correctly formatted. Each polygon in a multipolygon should be an array of linear rings, where the first ring is the outer boundary and any subsequent rings are holes. 2. **Superset Configuration**: Verify the configuration options in Superset's Deck.gl Polygon layer. Make sure that the "Polygon Column" and "Polygon Encoding" settings are correctly set to handle multipolygon data <sup>[[2]](https://github.com/apache/superset/blob/master/superset-frontend/plugins/legacy-preset-chart-deckgl/src/layers/Polygon/controlPanel.ts)</sup>. 3. **Simplification and Export**: If you are using Mapshaper to simplify the polygons before importing them into Superset, ensure that the simplification process is not removing small features that are necessary for the multipolygon to render correctly. 4. **Logs and Errors**: Check Superset's logs for any error messages that might indicate issues with rendering the multipolygon data. These steps should help you identify and resolve the visibility issue with your multipolygon data in Superset. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* --- <sup>Help Dosu learn!
