{"version":"1.0","type":"rich","title":"England Regional Map","description":"This example displays a choropleth-style map of English regions in pink, with neutral gray interior boundaries, rendered as an SVG using React. The map loads TopoJSON data via a custom `useData` hook, then converts it to GeoJSON with `feature` and `mesh` from topojson. The `Marks` component projects the geographic coordinates using `geoNaturalEarth1` and draws paths with `d3.geoPath`. The visualization demonstrates the integration of D3 v7’s geospatial utilities within a React component structure.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/22c82af773d04a558378f26aa636e1d2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
