This interactive visualization combines a world bubble map and a time-series histogram to explore migrant deaths and disappearances. Users can brush over the date histogram to filter the map, dynamically updating the displayed circles. The map uses a natural Earth projection via `d3.geoPath` and `d3.geoNaturalEarth1`, while the histogram uses `d3.bin` and `d3.brushX`. Data comes from a CSV of Missing Migrants Global records, rendered as SVG circles with `d3.scaleSqrt` sizing.
