Two coordinated views visualize migrant deaths and disappearances worldwide. A bubble map uses `d3.geoNaturalEarth1` and `d3.geoPath` to draw country boundaries, graticules, and scaled circles for filtered data. Below it, a time histogram built with `d3.bin` and `d3.scaleTime` shows monthly death totals; brushing with `d3.brushX` filters the map reactively, updating circles through React state. Data comes from a CSV of missing migrants, while country shapes use TopoJSON from the world-atlas package.
