This visualization shows global migrant deaths and disappearances over time and location. A brushed timeline at the bottom filters the bubble map above, which uses `d3.geoNaturalEarth1` and `d3.geoPath` to render world landmasses, with circle radii scaled by the total dead and missing per incident. The histogram uses `d3.bin`, `d3.scaleTime`, and `d3.brushX` to select date ranges, driving React state updates that filter the map’s displayed data.
