The map supports drag-to-pan and zoom interactions, using a geographic orthographic projection. It relies on D3’s `geoOrthographic` and `geoPath`, alongside Turf’s `booleanPointInPolygon` and an RBush spatial index for efficient point-in-polygon queries. Data comes from the 2023 Census Bureau shapefiles and American Community Survey demographics, both loaded as JSON.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6fb60d8a832f4d1e8d6239dac501d8ef?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
