{"version":"1.0","type":"rich","title":"Centered US Map","description":"This example displays a centered map of the United States with state boundaries highlighted in blue over a green landmass, set against a graticule grid and a light blue spherical backdrop. Using React and D3 v5, the visualization loads US Atlas TopoJSON data and converts it to GeoJSON features via topojson’s `feature` and `mesh` functions. The map is rendered through SVG paths generated by `d3.geoPath` with a `geoAlbers` projection, while `geoGraticule` creates the background grid lines.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1b13e7aa4da746668914069e9f8ea108?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
