A world map displays migrant deaths as green bubbles scaled by mortality count, synced with a brushing-enabled time histogram below. Dragging the histogram’s brush filters the map’s bubbles to show only incidents within the selected date range. Built with React and D3 v7, it uses `geoNaturalEarth1` and `geoPath` for the map, `scaleSqrt` for bubble sizing, and `brushX` with `scaleTime.invert` to link selections. Data comes from a CSV of reported migrant incidents.
