{"version":"1.0","type":"rich","title":"Fork of Sized Points on a Map","description":"A world map displays cities with populations over 50,000, sized proportionally to their population using a square root scale. The visualization renders a natural Earth projection with graticules, landmasses, and country borders in light gray tones. React manages the component structure while D3 v5 handles geographic projection via `geoNaturalEarth1`, path generation with `geoPath`, and CSV data loading from the Simplemaps World Cities Database. Semi-transparent teal circles overlay each city location, with their radii scaled to population values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c2ca0d3b45ea42d39816878cda3633e9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
