{"version":"1.0","type":"rich","title":"VarshaGSweden","description":"This example displays a choropleth-style map of Sweden’s counties, highlighting internal boundaries in cyan and county fill in dark blue on a light background. Using React with D3 v5, it loads TopoJSON data from a GitHub gist, converts it to GeoJSON with `topojson.feature`, and renders paths via `d3.geoPath` with a Mercator projection fitted to the viewport. Interior mesh lines are drawn separately using `topojson.mesh`. The visualization updates reactively when data loads.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dc653a78b2ca4eafba15cd69c8937cd8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
