{"version":"1.0","type":"rich","title":"World Map with Cities","description":"A world map displays the Earth's landmasses in green with a blue ocean, overlaid with circles representing cities from a CSV file, sized by population using a square-root scale. The visualization uses React and D3's `geoNaturalEarth1` and `geoPath` APIs to render the map, graticule, and city markers as SVG circles. City data is loaded via `d3.csv` from a remote URL.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/09759f96fd564a25a674402f2d1bfe98?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
