{"version":"1.0","type":"rich","title":"World Cities","description":"This visualization displays global cities as tiny dots on a natural Earth projection, overlaid with graticule lines and country outlines. It uses D3’s `geoNaturalEarth1`, `geoPath`, and `geoGraticule` to render the map, while `topojson-client` converts TopoJSON country boundaries. City coordinates are projected from latitude and longitude, and each dot’s radius is fixed at 0.2 pixels. Data comes from a reduced World Cities CSV and a 110m world atlas, loaded via `fetch` and parsed with `csvParse`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3354a8c1a19847a8b2f93afb932ff70b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
