{"version":"1.0","type":"rich","title":"Points on a Map","description":"A world map displays cities as semi-transparent teal circles, with circle size encoding population via a square-root scale. The map uses a Natural Earth projection with land masses, graticules, and country interiors rendered via `geoPath` and `geoGraticule` from D3. The React app loads TopoJSON from World Atlas and CSV city data, then projects coordinates through `geoNaturalEarth1` to position the SVG circles.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ecc385e72c4d46479f4ca1ad7da3be7e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
