{"version":"1.0","type":"rich","title":"map","description":"A map of Estonian counties rendered as an SVG using React and D3. The visualization uses a Mercator projection via `d3.geoMercator` and `d3.geoPath` with `fitExtent` to scale the map to the viewport. County boundaries are drawn as brown filled paths with darker stroke outlines, while interior borders are highlighted using a TopoJSON mesh. The geographic data is loaded from a remote TopoJSON file and processed with `feature` and `mesh` from the topojson library.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a3281359864f4f18891c2201548c1cc3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
