This visualization combines a world bubble map and a time-series histogram to explore migrant deaths globally. The map uses a natural Earth projection with `d3.geoPath` and `d3.geoNaturalEarth1` to plot points sized by `scaleSqrt` based on the "Total Dead and Missing" value. A `d3.brushX` on the timeline filters the map’s circles in real time, while `useMemo` optimizes rendering. Data comes from the Missing Migrants Project CSV, with country boundaries from World Atlas TopoJSON.
