This interactive visualization combines a world map of missing migrant incidents with a linked time-series histogram. The map uses a natural Earth projection rendered with `d3.geoPath` to plot bubble-scaled circles representing the total dead and missing at each location, while a brushable histogram below allows filtering the map by reported date. React hooks like `useMemo` optimize rendering performance, and the data comes from the Missing Migrants Project dataset. The visualization is built with React, D3 v5, and TopoJSON for country boundaries.
