{"version":"1.0","type":"rich","title":"Simple US County Map","description":"This example displays a map of US counties rendered as a collection of white-stroked polygons. It fetches TopoJSON data from the us-atlas CDN, converts it to GeoJSON using `topojson-client`’s `feature` function, and projects it with `geoAlbersUsaTerritories` from the `geo-albers-usa-territories` library. The map is drawn using `d3.geoPath` within a dynamic SVG container that resizes to the window, with state management driving the asynchronous data loading.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1381fcd27488491f8aac88d3d059ffb9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
