Fork of Migrant Deaths Linked Views with Fast Brushing
This interactive visualization links a world map of migrant deaths with a brushable time-series histogram, enabling filtering by date range. The map uses d3.geoNaturalEarth1 projection, d3.geoPath, and TopoJSON world atlas data, with bubble sizes scaled by total dead and missing via d3.scaleSqrt. The histogram aggregates monthly totals using d3.bin and d3.sum, while React’s useMemo and a d3.brushX selection provide fast linked brushing. Data comes from a CSV of Missing Migrants Global records.
