GeoJSON data contains arrays of coordinates that create polylines (like borders). You can find geoJSON data for the 50 U.S. state borders, for example. I would like proper geoJSON data for this: https://www.scribblemaps.com/create/#/id=HfPjzTz28R&lat=40.76084989&lng=-73.98615251&z=14&t=mbb_road
Does anyone know where I would find or commission this? It's going into a Kotlin-based web endpoint that creates maps.
