Fork of Migrant Deaths Linked Views with Fast Brushing
A linked-view visualization combines a world map with a date histogram to explore migrant deaths. The map uses D3's `geoNaturalEarth1` projection to plot cities as circles scaled by the number of deaths. The histogram uses `scaleTime` binning and a brush to filter the map's displayed data. The implementation leverages React's `useMemo` for performance and D3 v5, with SVG marks drawn via `geoPath`.
