This interactive visualization combines a world map and a time-series histogram to explore migrant deaths. The map displays circles sized by the number of dead and missing migrants, while the histogram shows monthly totals. Users can brush over the histogram to filter the map’s circles dynamically. The map uses `d3.geoNaturalEarth1` and `d3.geoPath` for geographic rendering, while the histogram employs `d3.brushX` and `d3.bin` for aggregation. React’s `useMemo` optimizes rendering performance. Data comes from the Missing Migrants Project CSV.
