{"version":"1.0","type":"rich","title":"Fork of USA Country Map","description":"This example displays a choropleth-style map of the 50 US states, rendered as an SVG where each state boundary is drawn using D3’s `geoPath` and a custom `geoAlbersUsaTerritories` projection. The map initially fills each state with a teal color, and hovering over a state highlights it in magenta. Data is loaded asynchronously from the US Atlas TopoJSON file (`states-10m.json`) using React hooks (`useState`, `useEffect`) and processed with TopoJSON’s `feature` and `mesh` functions to generate land and interior borders. The visualization is built with React 16 and D3 v5, 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/524b2dd32cc048379a5efdc0e833e950?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
