A world map visualization displays locations of missing migrants, with each circle's radius scaled by the square root of the reported total dead and missing, using a D3 projection. The map is rendered with SVG, leveraging React for the component structure and D3's geoEqualEarth projection, geoPath, and geoGraticule for the map elements. Circle sizes are determined by a sqrt scale, and the migrant data is loaded from a CSV via D3's csv function.
