This visualization combines a bubble map and a date histogram to explore global migrant deaths and disappearances. The map uses a `geoNaturalEarth1` projection with `geoPath` and `geoGraticule` to render world landmasses, while circle radii are scaled by the square root of the total dead and missing via `scaleSqrt`. The histogram below aggregates the same data monthly using `bin` with `timeMonths` thresholds, and employs `scaleTime` and `scaleLinear` for axes. Data is loaded from a CSV using `d3.csv`, with world geometry from TopoJSON.
