{"version":"1.0","type":"rich","title":"World Map","description":"A choropleth map of the United States colors individual states by population using a D3 threshold scale, with darker shades representing higher population values. The visualization loads geographic boundaries from a TopoJSON file via the `us-atlas` package and converts them to GeoJSON using `topojson.feature`. A `d3.geoAlbersUsa` projection is fitted to the SVG dimensions, and `d3.geoPath` renders each state as an SVG path. Population data for ten states is provided inline as a Map, with states lacking data shown in the lightest color.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ee133d0fb1a048a4a7c3f2c78c5b02e8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
