Developers used GPT-5.6-Sol, Claude Code, and Fable 5.1 to create the GeoJSON Map Viewer tool, which is used to display and export GeoJSON files in PNG format on maps. This tool successfully integrated the geographical boundary data of El Granada GCSD and Midcoast Community Council (located in Half Moon Bay, California). Users can view the overlay maps of these two regions through a link on the same interface.
