This visualization maps the global locations of missing migrants, with semitransparent circles sized proportionally to the total number of dead and missing at each coordinate. The map uses a natural Earth projection rendered with d3.geoPath, combining world landmasses, graticules, and country borders from the world-atlas TopoJSON dataset. The CSV data is loaded and parsed with d3.csv, while d3.scaleSqrt maps the migrant counts to circle radii. The React component structure uses useState and useEffect hooks to fetch and display the data as SVG circles.
