{"version":"1.0","type":"rich","title":"State Ratings Map","description":"This example renders a choropleth map of the United States using D3’s geo APIs. It employs `d3.geoAlbersUsa` for the projection, `d3.geoPath` to draw state boundaries, and `d3.geoGraticule` to overlay a graticule and outline. State geometries come from a TopoJSON source, converted to GeoJSON via `topojson-client`’s `feature` function. The visualization uses a join-based workflow to create SVG paths, with a white stroke separating states and a light gray graticule.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ae7a80c87a1f4cd6ad1ca19c713495f2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
