{"version":"1.0","type":"rich","title":"World Map - React & D3","description":"This map visualization displays global cities with scaled square-root population marks overlaid on a land-based world map. Built with React and D3 v5, it renders an SVG projection using `d3.geoMercator()` and `d3.geoPath` with graticules, land features, and interior boundaries. City data comes from a CSV file, and population values drive symbol sizing via `d3.scaleSqrt`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c39a54079f7249ae9077152750cbeb50?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
