This interactive visualization combines a world map of migrant deaths with a linked time-series histogram, enabling rapid filtering through brushing. The map uses a natural Earth projection with `d3.geoPath` to render country boundaries and graticules, while circles sized by `d3.scaleSqrt` represent the total dead and missing per location. The histogram aggregates monthly totals using `d3.bin` and `d3.timeMonths`, with a `d3.brushX` selection that instantly filters the map’s displayed data. Built with React hooks and D3 v5, it renders in SVG from a subset of the Missing Migrants Global dataset.
