This interactive visualization combines a bubble map and a date histogram to explore global migrant deaths and disappearances. The map projects circles scaled by the square root of the reported total, using `geoNaturalEarth1` and `geoPath` for geographic rendering. The histogram aggregates incidents by month, with a `brushX` component filtering the map data based on the selected time range. City and country boundaries come from the World Atlas TopoJSON dataset, while the migrant data is loaded via `d3.csv`.
