{"version":"1.0","type":"rich","title":"Gist 8393671","description":"A single county subdivision polygon from a GeoJSON file is rendered on a map, with its geographic boundary drawn as a closed path and a marker placed at its centroid coordinates. The visualization uses D3’s `d3.geoPath` to project the polygon’s coordinates onto a 2D canvas, while the latitude and longitude properties from the GeoJSON feature are plotted as a point. The code relies on standard D3 projection and path-generation APIs, displaying the raw geometry 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-8393671?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
