{"version":"1.0","type":"rich","title":"Points on World Map","description":"This visualization displays a Natural Earth projection world map with semi-transparent circles sized by city population. The map renders landmasses, country borders, and graticules using d3.geoPath and d3.geoNaturalEarth1, with data from World Atlas TopoJSON. City locations and populations come from a CSV file, with circle radii scaled by d3.scaleSqrt. The React component structure uses hooks to load both datasets asynchronously, and all marks are drawn as SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bc415485899b431f940bc9f723d01cc9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
