This interactive visualization combines a bubble map and a brushing-linked date histogram to explore migrant deaths recorded in 2019. The map uses a natural Earth projection with `d3.geoPath` to render country boundaries and graticules, while circle size encodes the total dead and missing per location. The histogram aggregates deaths by month using `d3.bin` and `d3.timeMonths`. Users can brush over the time axis with `d3.brushX`, filtering the map’s circles to show only incidents within the selected date range. Data comes from a CSV of the Missing Migrants Project, rendered as SVG with React’s `useMemo` for performance.
