{"version":"1.0","type":"rich","title":"Cities on the World Map","description":"This visualization displays cities as semi-transparent circles on a natural Earth projection, with circle size encoding population using a square-root scale. It renders world land masses, graticules, and country interiors via `geoPath` and `geoNaturalEarth1`, while city positions are projected from latitude and longitude coordinates. Data comes from a CSV of world cities loaded with `d3.csv`, and the world atlas TopoJSON is parsed using `feature` and `mesh` from topojson. React manages the component state, with D3 version 7 providing all geographic and scaling utilities.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/801ce5e0ef3a49a880ee852858fde900?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
