{"version":"1.0","type":"rich","title":"Let's make a map US-counties with D3.js!","description":"This example renders a choropleth-style map of all US counties as light green SVG paths with subtle black borders. It uses D3 v5’s `geoAlbersUsa` projection and `geoPath` generator to convert TopoJSON county boundaries from the `us-atlas` dataset into scalable vector graphics. The code loads the TopoJSON via `d3.json`, extracts features with `topojson.feature`, and binds them to SVG path elements, while styling is handled with CSS class selectors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/921596f9754742bc8d95ee96b9bb49ef?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
