A world map displays the global distribution of missing migrants, with circle size encoding the total number dead or missing for each location. A time-series histogram below the map shows the monthly count of missing migrants, and brushing on this histogram filters the map’s circles to the selected date range. The visualization uses React for component structure, D3's `geoNaturalEarth1` projection and `geoPath` for map rendering, `scaleSqrt` for circle sizing, and a D3 `brushX` to control filtering. Data comes from the Missing Migrants Project CSV, with country boundaries from World Atlas TopoJSON.
