A linked-view visualization combines a bubble map and a time-series histogram to explore migrant deaths. The map projects incident locations using a natural Earth projection, with bubble size scaled by the square root of total dead and missing. A brush on the histogram filters the map's bubbles in real time. The code uses `d3.geoNaturalEarth1`, `d3.geoPath`, `d3.brushX`, and React's `useMemo` for efficient recomputation. Data comes from the Missing Migrants Project, and the visualization leverages D3 v5 and React for rendering.
