{"version":"1.0","type":"rich","title":"Sweden map","description":"This example presents a choropleth-style map of Sweden’s counties, rendered as SVG paths with dark blue fills and gold interior borders. The visualization uses React to manage state and D3 v5’s `geoMercator` projection with `geoPath` and `fitExtent` to scale and center the map. County boundaries and interior borders are derived from a TopoJSON file using `topojson.feature` and `topojson.mesh`. The code includes a commented-out `geoEqualEarth` alternative and a video link, though the active map focuses solely on geographic outlines without additional data encoding.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6ef86788cd5a4936ae7b179a0e661739?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
