This example shows missing migrant deaths and disappearances on a world map, with a time-series histogram below displaying monthly totals. Brushing across the histogram filters the map’s circles to only show incidents within the selected date range. The map uses `d3.geoNaturalEarth1` and `d3.geoPath` with World Atlas TopoJSON, while the histogram uses `d3.bin` and `d3.brushX`. React manages state, and data comes from a CSV of missing migrant records.
