This visualization combines a bubble map and a date histogram to show migrant deaths and disappearances. The map uses `geoNaturalEarth1` and `geoPath` to render world boundaries with circles scaled by `scaleSqrt`, while the histogram bins reported dates with `d3.histogram` and sums death counts per month. Data comes from the Missing Migrants Project CSV, loaded via `d3.csv`. Both views are rendered as SVG within a React app using `d3.scaleTime` and `d3.scaleLinear`.
