Add support for static image backgrounds in MapBox chart

What is the problem or goal the end user is trying to solve or accomplish?

The user wants to visualize custom polygons over a static background image (e.g., a floorplan or schematic) instead of a geographical map. This is useful in contexts where spatial data is non-geographic, such as factory layouts, indoor maps, or conceptual diagrams.

How are they solving it currently?

They attempted to use MapBox with custom styles, but Preset currently does not expose functionality to upload or reference custom MapBox styles or raster/image overlays. There is no built-in way to replace the base map with a custom image while preserving polygon rendering.

What is the recommended solution by the Customer?

They would like the existing MapBox chart to support the option to:

- Use a static background image in place of a geographic map

- Define bounds to align the image with polygon coordinates

- Optionally disable or hide default MapBox baselayers

This would allow them to render custom shapes on top of floorplans or other non-map images using the same MapBox chart logic and interactivity.
