{"version":"1.0","type":"rich","title":"US Map practice","description":"This example shows a static map of US counties and state boundaries rendered in SVG, with each county path filled in grey and state interior borders drawn in a distinct teal color. The visualization uses D3 v5’s `geoPath` with a `geoIdentity` projection that applies `reflectY(true)` to flip the map vertically. React components load TopoJSON from the US Atlas package (`counties-albers-10m.json`), converting it to GeoJSON features via `feature` and `mesh` from TopoJSON, then fitting the projection to a 960×500 viewport with `fitExtent`. The map includes county polygons and state outline meshes, with styling defined in an external CSS file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/74296f8622bf449aad21c4cce387f6a2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
