This visualization combines a natural Earth projection bubble map with a linked time-series histogram to explore migrant deaths and missing persons. The map uses `d3.geoNaturalEarth1` and `d3.geoPath` to render country boundaries from World Atlas TopoJSON, with circle sizes scaled by total dead and missing via `d3.scaleSqrt`. A brushable histogram using `d3.brushX` filters map points by reported date, while React’s `useMemo` optimizes rendering performance. Data comes from the Missing Migrants Project CSV subset.
