Migrant Deaths
This interactive visualization maps global migrant deaths and missing persons over time. It combines a natural Earth projection world map with proportional circles, sized by the total dead and missing, and a linked time-series histogram that filters the map via a brush. The D3 libraries `geoNaturalEarth1`, `geoPath`, and `geoGraticule` render the map, while `scaleSqrt` and `scaleTime` manage the encodings. Built with React, it uses `useMemo` for performance and loads data from a CSV of migration incidents and a World Atlas TopoJSON.
