{"version":"1.0","type":"rich","title":"Fork of Polished World Map(cities)","description":"This D3 visualization presents a world map with city points sized by population, using a Natural Earth projection with graticules, sphere, and country interiors. Built with React, the code uses `geoNaturalEarth1`, `geoPath`, and `geoGraticule` from D3, along with a `scaleSqrt` for circle radii. City data is loaded from a CSV of world cities, while country boundaries come from World Atlas TopoJSON, both rendered as SVG paths and circles.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e295a4c1b5234df99195dbf17ee18a4b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
