Migrant Deaths Linked Views with Brushing
This visualization displays migrant deaths worldwide, with a bubble map showing the total dead and missing per location alongside a linked time series histogram. Users brush the date histogram to filter the map’s circles, revealing how fatalities vary over time. Built with React and d3.v5, it uses `d3.geoNaturalEarth1` and `d3.geoPath` for the map, `d3.scaleSqrt` for circle sizing, and `d3.brushX` to coordinate the linked views. Data comes from a CSV of migrant death records with country boundaries from World Atlas TopoJSON.
