{"version":"1.0","type":"rich","title":"SPAC Sized Points on a Map","description":"This map displays cities with populations over 50,000 as semi-transparent circles, sized proportionally to their post-SPAC ticker symbol count using a square-root scale. The visualization uses D3’s `geoNaturalEarth1` projection and `geoPath` to render landmasses, graticules, and country interiors from World Atlas TopoJSON data. City coordinates are projected from latitude and longitude, with each circle rendered as an SVG element in React. Hovering reveals a native tooltip showing the city name and count. City data originates from Simplemaps’ World Cities Database.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7dd7dc8cbbe740d2aa48e5ca13ffdd5f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
