Migrant Deaths Linked Views with Brushing
This visualization links a geographic bubble map of migrant deaths with a time-series histogram, using brushing to filter data across both views. The map plots circles sized by the "Total Dead and Missing" count, while the histogram aggregates deaths by reported date. Selecting a time range in the histogram filters the map to show only incidents within that period. The implementation uses React with `useMemo` for performance, D3 v5 APIs including `geoNaturalEarth1`, `geoPath`, `scaleSqrt`, `scaleTime`, `histogram`, and `brushX`, and renders as an SVG with data from a CSV and world-atlas TopoJSON.
