{"version":"1.0","type":"rich","title":"Sweden map","description":"This example visualizes the counties of Sweden as a choropleth map, using a red fill for each county and yellow lines to highlight interior borders. The map is rendered as an SVG using React, with geographic data from a remote TopoJSON file. The code employs `topojson.feature` and `topojson.mesh` to extract county boundaries and interior edges, and `d3.geoPath` with the Mercator projection to project the geometries. The projection is fitted to the map's extent using `fitExtent`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d1a70087b1c149c0bcac436ae6247e4b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
