{"version":"1.0","type":"rich","title":"England Regional Map","description":"This example displays a map of England with its geographical regions highlighted in green and internal boundaries in yellow. Built with React and D3 v7, it uses `d3.geoNaturalEarth1` for projection and `d3.geoPath` to render TopoJSON features. The data is loaded from a GitHub gist via `d3.json` and processed with the `topojson` library’s `feature` and `mesh` functions. The visualization renders as an SVG, with the `Marks` component generating styled path elements for each region and interior border.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ae0fd2d703ac4fa1af82f9c73568d9e2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
