This visualization combines a world map and a time-series histogram to explore 37 migrant deaths. The map uses a natural Earth projection via D3’s `geoNaturalEarth1` and `geoPath` to render land and graticules, with circles sized by `scaleSqrt` proportional to death counts. The histogram aggregates monthly totals using `d3.bin` and `sum`, while a `brushX` brush filters the map’s data in real-time through React state. Data comes from the Missing Migrants Global subset CSV, and React’s `useMemo` optimizes rendering performance.
