{"version":"1.0","type":"rich","title":"Worldmap with cities","description":"This example displays a world map using a Natural Earth projection, with the landmasses rendered as gray polygons and graticules overlaid. City locations are plotted as semi-transparent circles, with their radius scaled by the square root of each city's population. Built with React, the visualization uses D3.js modules `geoNaturalEarth1`, `geoPath`, and `geoGraticule` for the map projections and graticule, while `scaleSqrt` maps population values to circle sizes. City data is loaded from a CSV file, and world atlas geometries are fetched as TopoJSON, which is processed through `topojson` functions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6f23ebd2352f494fad588cee155746e0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
