Fork of Migrant Deaths Linked Views with Fast Brushing
A choropleth-style bubble map renders global migrant deaths as circles sized by total dead and missing, alongside a date histogram that filters the map via brushed time ranges. The visualization uses React's `useMemo` for performance, D3 v5's `geoNaturalEarth1` projection and `geoPath` for the map, and `brushX` with `select` for interactive filtering. Data comes from a Missing Migrants CSV, with country boundaries from the World Atlas TopoJSON.
