{"version":"1.0","type":"rich","title":"World map","description":"A world map visualization displays global cities as semi-transparent circles, with the circle size proportionally representing each city's population, layered over a graticule and world atlas landmasses. The example uses React to render SVG paths for the sphere, graticules, and land features, while city markers are positioned via the `geoMercator` projection. Population data from the Data Canvas Sense Your City Dataset is mapped to radius using `d3.scaleSqrt`, with the `d3.geoPath` and `d3.geoGraticule` APIs handling geographic geometry.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/55060659ecbd4a73909c72f3e6b0b8c5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
