This visualization combines a world map with a temporal histogram to show migration-related fatalities. The map uses D3 geoNaturalEarth1 projection with geoPath to render landmasses and graticules, while scaled circles represent total dead and missing per location. The histogram bins reported dates into monthly intervals using d3.histogram, with a brushX selection filtering the map’s displayed data. React manages state and component rendering, fetching CSV data and TopoJSON world atlas via custom hooks.
