This interactive visualization combines a world map and a time-series histogram to explore data on missing migrants. Brushing on the histogram filters the map’s bubble marks, which are sized by the total dead and missing using a square-root scale. The map uses `d3.geoNaturalEarth1` and `d3.geoPath` to render land and graticules from TopoJSON, while the histogram employs `d3.bin`, `d3.brushX`, and scales for time and linear values. React manages state and rendering, with D3 v5 handling data loading and axes.
