{"version":"1.0","type":"rich","title":"Missing Migrants size on Map","description":"This visualization displays a world map with circles representing cities, where the circle size encodes population using a square root scale. The map uses D3's `geoNaturalEarth1` projection and `geoPath` to render land masses, graticules, and country boundaries from World Atlas TopoJSON. City coordinates from the Missing Migrants dataset are projected and drawn as React-managed SVG circles with `scaleSqrt` determining radius. The visualization is built with React 16.9 and D3 v5, featuring styled land and sphere paths with semi-transparent teal circles.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/204ce67e3346422c9f2b5626ad4d3fb7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
