{"version":"1.0","type":"rich","title":"Gist 8393730","description":"This example uses a GeoJSON FeatureCollection of three census tract polygons in Loudoun County, Virginia, to visualize geographic boundaries. The code loads the tract geometries and renders them with d3.geoPath, projecting the coordinates onto a map. It displays the tract shape as an outlined polygon, with each feature’s properties (such as GEOID10 and centroid latitude/longitude) available for potential labeling or styling. The visualization relies on D3’s geographic projection and path generation to draw the vector data directly onto an SVG canvas.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-8393730?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
