A world map displays the total number of dead and missing migrants by location, with circle size encoding the count. A linked date histogram beneath the map allows brushing to filter the map to a selected time range. The visualization uses React with D3 v5, including `geoNaturalEarth1` and `geoPath` for map projection, `scaleSqrt` for circle sizing, and `brushX` for interactive filtering. Data comes from the Missing Migrants Project, with country boundaries from World Atlas TopoJSON.
