{"version":"1.0","type":"rich","title":"Gist 8393733","description":"This example visualizes U.S. Census tract 51700030800 in Virginia by rendering its four polygon sub-features as a geographic map. It uses D3.js with `d3.geoPath` to project and draw the GeoJSON geometry onto a canvas, displaying the tract boundaries and sub-tract divisions. The code loads the local `tract51700030800.geojson` file, which contains polygon coordinates with associated latitude, longitude, and tract identifiers, and plots them in a simple top-down view without additional styling or interaction.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-8393733?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
