This example combines a bubble map and a time-series histogram to visualize global migrant deaths and disappearances. The map uses `geoNaturalEarth1` and `geoPath` from d3-geo to project circle markers scaled by the square root of the death count, while the histogram uses d3’s `bin` and `scaleTime` to aggregate reported dates. React components structure the SVG, with data loaded via d3-fetch from a CSV of the Missing Migrants Project.
