A world map displays the locations of missing migrant incidents, with circles sized by the number of dead and missing using a square root scale. The visualization uses d3.geoNaturalEarth1 and d3.geoPath for map rendering, with country boundaries and graticules from TopoJSON. React components manage state and rendering, while d3.csv loads the migrant dataset. Point positions derive from latitude and longitude coordinates, and circle opacity is fixed at 0.3 for visual clarity.
