This visualization presents migration incidents worldwide as a bubble map, with circle sizes proportional to the total dead and missing per location, overlaid on a world atlas rendered with `d3.geoNaturalEarth1` and `d3.geoPath`. A linked date histogram below aggregates monthly totals, and its `d3.brushX` interaction filters the map in real time based on brush selection, updating circles to show only incidents within the chosen time range. The app uses React for state management, D3 v7 for scales, binning, and geographic rendering, and loads missing migrant data from a CSV file.
