This example presents a linked-view visualization of migrant deaths using a world map and a time-series histogram. A bubble map shows the geographic distribution of fatalities, while a brushed date histogram filters the map to show data within a selected time range. The visualization uses React with `useMemo` for performance optimization, D3 v5 for map projection (`geoNaturalEarth1`), geographic paths (`geoPath`), and scales (`scaleSqrt`, `scaleTime`), as well as `brushX` for interactive brushing. Data is loaded from a CSV dataset, and country boundaries come from World Atlas TopoJSON.
