{"version":"1.0","type":"rich","title":"Fork of Sized Points on a Map","description":"This example visualizes cities worldwide with populations exceeding 50,000, using point size to represent population magnitude. A natural Earth projection displays country boundaries and graticules, while semi-transparent teal circles overlay city locations. The visualization uses React components with D3's `geoNaturalEarth1` projection, `geoPath`, and `geoGraticule` for map rendering, and `scaleSqrt` for mapping population values to circle radii. City data originates from Simplemaps, and country boundaries come from the World Atlas TopoJSON source, rendered as SVG paths within a React application using d3.v5.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1a83f5cc07de4edd8781dc17f858553e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
