The visualization displays the global distribution of missing migrants and their incident dates, using a world map and a linked time-series histogram. Brushing a time range in the histogram filters the map’s circles, which are sized by the total number of dead and missing per incident. The map uses `d3.geoEqualEarth` projection, `d3.geoPath`, and `d3.geoGraticule`, while the histogram applies `d3.bin` and `d3.brushX`. Data comes from a CSV of missing migrant incidents up to 2021.
