A choropleth-free geographic map of Swedish counties displays land area in yellow with blue interior boundaries and a light blue sphere background, rendered as SVG paths. The visualization uses React for component structure, d3.geoMercator with fitExtent for projection, and d3.geoPath to draw features and interiors from TopoJSON data loaded via d3.json. County borders are emphasized through a mesh computed with topojson.mesh, distinguishing shared boundaries from external edges.
