This example combines a bubble map with a date histogram to visualize missing migrants data. The map uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to render world landmasses, graticules, and country borders, with circle sizes scaled by `d3.scaleSqrt` based on the total dead and missing. The histogram below bins reported dates into monthly intervals using `d3.histogram` and `d3.timeMonths`, summing casualties per bin with `d3.sum`. Both views render as SVG within a React component structure, pulling data from a CSV of migrant incidents and TopoJSON world atlas boundaries.
