{"version":"1.0","type":"rich","title":"Points on a Map","description":"A world map displays cities scaled by population using semi-transparent teal circles. The visualization renders geographic landmasses, graticules, and interior borders via d3.geoPath with a Natural Earth projection, while a d3.scaleSqrt maps population values to circle radii. City locations are projected from latitude and longitude coordinates, and data is loaded from a CSV using d3.csv. The React application overlays these marks on an SVG canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5292e23ba9254087802a0b37f97abdc0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
