This interactive visualization tracks migrant deaths and disappearances worldwide, combining a bubble map with a date histogram. Brushing a time range on the histogram filters the map’s circles, which are scaled by death counts per location. The map uses `d3.geoPath` with Natural Earth land and graticules, while the histogram applies `d3.histogram` and `d3.brushX`. Country boundaries come from the World Atlas TopoJSON, and migration data is loaded from a CSV via `d3.csv`.
