{"version":"1.0","type":"rich","title":"world map w/ cities","description":"This visualization displays a world map with cities whose populations exceed 50,000, using a natural Earth projection that spins to reveal different hemispheres. The map incorporates country boundaries, interior borders, graticules, and geographic lines, with land areas filled by an animated pattern. City markers are sized by population using a square-root scale, while country boundaries include tooltips on hover. The project uses React with D3’s `geoNaturalEarth1`, `geoPath`, and `geoGraticule`, sourcing city data from Simplemaps and country shapes from World Atlas TopoJSON, all rendered as SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9242def3e1a647579b5f9a9e32667d41?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
