{"version":"1.0","type":"rich","title":"Centered US Map","description":"This map of the United States uses an Albers equal-area projection to display state boundaries and the national border, overlaid on a sphere and graticule for context. The visualization is built with React and D3 v5, using `d3.geoAlbers`, `d3.geoPath`, and `d3.geoGraticule` to render the geographic features as SVG paths. State data originates from the US Atlas TopoJSON, with outlines colored distinctly from the land and sphere fill, and the map is generated from TopoJSON topology for state interiors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5bcb6eafc1fa405f8254d49c6b0d52cb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
