Migrant Deaths Linked Views with Brushing
This visualization presents migrant deaths worldwide through a linked-view design. A world map displays proportional circles representing total dead and missing individuals, using a square root scale for sizing. Below, a histogram aggregates the same data by month, with brushing enabled through `d3.brushX` to filter the map’s circles based on the selected time range. The map is rendered with `d3.geoNaturalEarth1` and `d3.geoPath`, while React’s `useMemo` optimizes rendering. Data comes from the Missing Migrants Project CSV, with country boundaries from World Atlas TopoJSON.
