This visualization combines a world map of missing migrant incidents with a brushing-linked time histogram. It uses D3’s `geoNaturalEarth1` and `geoPath` to render country boundaries and graticules, while circle size reflects death tolls via `scaleSqrt`. A `brushX` interaction filters the map by date range selected in the histogram. Built with React and D3 v5, the data comes from a CSV of global missing migrants, with the map optimized through `useMemo`.
