A dashboard maps migrant deaths worldwide alongside a time-series histogram, with a linked brush filtering the map’s circles by date range. Built with React and D3 v7, it uses `geoNaturalEarth1` and `geoPath` for the map, `scaleSqrt` for circle sizing, and `brushX` for interactive filtering. The histogram aggregates monthly totals via `bin` and `timeMonths`, with axes rendered from `scaleTime` and `scaleLinear`. Data comes from the Missing Migrants Project CSV, with geographic boundaries from TopoJSON.
