A world map displays migrant deaths and missing persons as scaled bubbles, with a time-series histogram below showing monthly totals. Brushing on the histogram is initiated via `brushX`, though only logging to the console. The visualization uses `geoNaturalEarth1` and `geoPath` for the map, `scaleSqrt` for bubble sizing, and `histogram` with `timeMonths` thresholds for binning. Data comes from the Missing Migrants Project CSV, rendered with React and D3 v5 in SVG.
