{"version":"1.0","type":"rich","title":"DLF Project Map","description":"This interactive map overlays two historical raster layers—a 1939 HOLC map and a 1965 Watts map—on a Mapbox GL base map, with sliders controlling each layer’s opacity. A third layer from the 1947 Green Book displays point features; clicking a point opens a popup with its name and type. Built with Mapbox GL JS, the map uses raster sources from Mapbox tilesets and queryRenderedFeatures for interactivity.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-e1564ba91465bdd495905225b86259dc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
