{"version":"1.0","type":"rich","title":"Fork of Points on a Map","description":"This visualization displays a world map with city points scaled by population using a square-root scale, rendered using D3.js geo projections and React. The map shows land masses, graticules, and a sphere outline created with the `geoNaturalEarth1` projection and `geoPath` from D3. City data is loaded from a CSV via `d3.csv`, while world atlas topology is fetched and processed with `topojson`’s `feature` and `mesh` functions. The visualization uses SVG circles with a gold fill at reduced opacity to represent city populations, all set against a dark radial-gradient background.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6cfae4e9cb7a42c4960adcc614dbf63e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
