{"version":"1.0","type":"rich","title":"Fork of world map w/ cities & countries pop!","description":"This visualization displays a world map with cities exceeding 50,000 population and country-level population data. Cities appear as scaled circles based on population, while countries vary in opacity according to their population figures. The map uses React with d3-geo-projection’s `geoNaturalEarth1` projection and `geoPath` for rendering. City data comes from Simplemaps, country boundaries from World Atlas TopoJSON, and population values from a UN 2019 dataset. Additional geographic lines and graticules enhance the map’s spatial context.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/743282f10c4b4a8f8c4ca2c91136079c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
