{"version":"1.0","type":"rich","title":"Fork of Fork of Swedish map","description":"This example displays a map of Swedish counties using a Mercator projection, rendered as black filled regions with white internal borders against a silver stroke. Built with React and D3 v5, the code leverages `d3.geoPath` for path generation and `topojson` to extract features and interior boundaries from the GeoJSON source. The visualization highlights the country’s administrative subdivisions through a minimal, high-contrast styling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ca621cca2d56496698d30f0a501258e0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
