{"version":"1.0","type":"rich","title":"Swedish map","description":"This example displays a choropleth map of Swedish counties using SVG paths generated from TopoJSON data. The visualization loads geojson features from a UK counties dataset and renders them with D3’s geoMercator projection and geoPath. Built with React, the map uses a custom `useData` hook to fetch and transform the topology, while the `Map` component iterates over features to draw each region. The code demonstrates ES6 module imports, D3 integration via UNPKG, and React state management for asynchronous data loading.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5ae8782eb5464d0d9ce2850b8b19008f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
