This visualization combines a world map with a date histogram to show the locations and timing of migrant deaths and disappearances. The map uses a natural Earth projection with graticules, country boundaries, and semi-transparent circles scaled by the total dead and missing count. The histogram below aggregates the same metric by month, using d3.bin and d3.timeMonths. The data comes from a CSV of missing migrants, and the map is rendered with d3.geoPath and TopoJSON world atlas data.
