{"version":"1.0","type":"rich","title":"Swedish map","description":"This visualization displays the counties of Sweden using a geographic map rendered with SVG. The map fills the entire viewport via a Mercator projection fit to the data extent, with each county filled red and internal boundaries highlighted in purple. The implementation uses d3-geo’s `geoMercator`, `geoPath`, and `fitExtent` to project GeoJSON features derived from a TopoJSON source via topojson’s `feature` and `mesh` functions. React manages the component state and renders the paths, while data is loaded asynchronously with `d3.json`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1b8870b3ed61448d80d1067b880ebb35?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
