Migrant Deaths Linked Views with Brushing
This interactive visualization presents migrant deaths through two linked views: a world map with proportional circles and a time-series histogram. Users brush a date range in the histogram to filter which data points appear on the map. Built with React and D3 v5, the map uses d3.geoNaturalEarth1 and d3.geoPath for geographic rendering, while the histogram employs d3.histogram, d3.scaleTime, and d3.brushX for interactive filtering. Data comes from the Missing Migrants Project, with country boundaries from World Atlas TopoJSON.
