A composite visualization combines a bubble map with a time-series histogram to show global migrant deaths and disappearances. The map uses `d3.geoNaturalEarth1` and `d3.geoPath` to render country boundaries and graticules, with circle areas scaled by `d3.scaleSqrt` based on total dead and missing. The histogram bins reported dates by month using `d3.bin` and `d3.timeMonths`, summing casualties per bin. Both views use React and D3 v5, drawing to SVG, with data from the Missing Migrants Project.
