{"version":"1.0","type":"rich","title":"Cities of the World","description":"Cities of the World uses a natural Earth projection to display global population data as proportional circles. D3’s geoNaturalEarth1 and geoPath render landmasses, graticules, and sphere outlines, while a sqrt scale maps city populations to circle radii. The visualization loads world atlas topology from world-atlas and city CSV data, overlaying semi-transparent dots atop a muted map. React manages the SVG rendering, with d3.v5 providing the underlying geospatial and scaling utilities.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9ae65c87e4874712b1dc8c6aa211a5cf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
