{"version":"1.0","type":"rich","title":"Centered US Map","description":"This visualization displays a map of the United States centered using the Albers equal-area projection. It shows the nation’s landmass with a colored fill, state boundaries as thin strokes, and a graticule sphere outline. Built with React and D3 v5, it loads US Atlas TopoJSON data via `d3.json` and uses `topojson.feature` and `topojson.mesh` to extract land and interior boundaries. The map is rendered as SVG paths generated by `d3.geoPath` with `geoAlbers`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/acd3ef4b04ff4f0db4287763cfbfd1b0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
