This visualization combines a world map and a time-series histogram to explore the Missing Migrants Dataset. A bubble map plots each migrant death or disappearance event, with circle radius scaled by the total dead and missing count using `d3.scaleSqrt`. Below, a bar chart aggregates deaths by month, and users can brush over the time axis with `d3.brushX` to filter the map, highlighting events within the selected date range. The map uses `d3.geoNaturalEarth1` and `d3.geoPath` with world-atlas TopoJSON data, while the React components manage state and rendering.
