Migrant Deaths Linked Views with Brushing
This visualization presents migrant deaths on a world map using a bubble chart, with a linked time-series histogram below for brushing. It shows the geographic distribution of the “Total Dead and Missing” metric, sized with `d3.scaleSqrt`, while the histogram aggregates deaths by month. Users can brush the histogram to filter map bubbles. Built with React and D3 v5, it uses `d3.geoNaturalEarth1` projection, `topojson` for land and interior boundaries, and `d3.brushX` for interactive selection. Data comes from the Missing Migrants Project.
