This interactive visualization combines a natural Earth projection map with a time-series histogram to explore missing migrants globally. The map uses `d3.geoNaturalEarth1` and `geoPath` to render circle marks scaled by the square root of casualties, while the histogram aggregates monthly totals using `d3.bin` and `scaleTime`. A `brushX` brush on the histogram filters the map’s data by date range, demonstrating linked views within a single SVG rendered with React and D3 v5. Data comes from the Missing Migrants Project CSV, with country boundaries from World Atlas TopoJSON.
