{"version":"1.0","type":"rich","title":"Dataviz 10 - Points on map with sizes","description":"A world map displays global cities with populations over 50,000, using circle size to encode each city’s population. The visualization uses a Natural Earth projection via `geoNaturalEarth1` and `geoPath` to render landmasses, country interiors, graticules, and a sphere backdrop. City coordinates are projected onto the map, and circle radii are scaled with `scaleSqrt` based on population data from Simplemaps. Built with React and d3.v5, the SVG rendering includes styled land, sphere, and interior boundary paths for a polished cartographic appearance.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/483ccf583e394b0683c006992324b299?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
