{"version":"1.0","type":"rich","title":"New York Map","description":"This map of New York census tracts uses a green sequential color scale to show the concentration of white residents per tract, with darker greens indicating higher counts. The visualization fetches census tract boundaries as TopoJSON and demographic data from the American Community Survey API, then joins them by tract ID. The code uses d3.geoPath to render the SVG paths and d3.scaleSequential with interpolateGreens for color encoding, while d3.zoom enables interactive panning and zooming of the map.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/adef2f8f2bdc40eea4474f5ffdff83b8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
