This visualization combines a bubble map and a date histogram to explore migrant deaths. The map uses a natural Earth projection to display circles sized by the total dead and missing, while the histogram aggregates the same data by month. A brush on the histogram filters the map’s circles, using React’s `useMemo` for efficient updates. The implementation leverages D3 v5 APIs like `geoNaturalEarth1`, `scaleSqrt`, and `brushX`, with data from the Missing Migrants Project and country boundaries from World Atlas TopoJSON.
