{"version":"1.0","type":"rich","title":"Points on the map original","description":"This visualization displays a world map with circles representing cities having populations greater than 50,000, with circle size scaled by population using a square root scale. The map includes landmasses, graticules, and sphere outlines rendered as SVG paths projected via `d3.geoNaturalEarth1` and `d3.geoPath`. Country boundaries come from the World Atlas TopoJSON, while city data originates from Simplemaps. Circles are semi-transparent teal, with opacity allowing overlap visualization. The code uses React with `d3.csv` for city data loading and `topojson.feature` and `topojson.mesh` for geographical features.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a58b485eff9945a0993c6c2f849a56da?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
