This visualization links a world map and a time-series histogram to explore migrant deaths. The map uses a Natural Earth projection with circle sizes scaled by the square root of death counts, while the histogram aggregates total deaths by month. A brush on the histogram filters the map’s data. Built with React and D3 (v5), it uses `d3.geoPath`, `d3.scaleSqrt`, `d3.histogram`, and `d3.brushX`. Data comes from a CSV of Missing Migrants records.
