Missing Migrants size on Map
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.
