{"version":"1.0","type":"rich","title":"Cars Report","description":"This visualization presents a world map highlighting cities with populations over 50,000, with circles sized by population. The map uses a natural Earth projection via `d3.geoPath` and `d3.geoNaturalEarth1`, displaying land boundaries, graticules, and country interiors. City data comes from Simplemaps, loaded as CSV with `d3.csv`, while country boundaries use TopoJSON from the world-atlas package. The visual style, including translucent teal circles and light gray fills, is defined in CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/97b89f59edb54f85a41237d74019a8c3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
