{"version":"1.0","type":"rich","title":"World Cities","description":"This visualization displays a world map with cities of 50,000 or more inhabitants, sourced from the World Cities Database. The map is rendered using D3’s `geoNaturalEarth1` projection with `geoPath`, while landmasses and internal country borders come from a TopoJSON world atlas. City positions are computed by projecting latitude and longitude coordinates, and are drawn as small circles. The code uses `d3.csvParse` for data loading and `topojson-client` to convert topology into GeoJSON features.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a43042eecf104d84a778c9a7fc02c563?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
