{"version":"1.0","type":"rich","title":"DLF Project Map","description":"This interactive map overlays two historical raster layers—HOLC 1939 redlining maps and Watts 1965—on a Mapbox GL base map centered on Los Angeles. Two range sliders control the opacity of each layer independently, allowing visual comparison of neighborhood classifications and later urban conditions. A clickable Green Book layer displays point features with popups showing property type and name. The visualization uses the Mapbox GL JS API with raster sources and setPaintProperty for opacity adjustments.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-272227132ac5acd0386b3ac1639d3e18?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
