Migrant Deaths Linked Views with Brushing
This interactive visualization shows migrant deaths and missing persons over time and location on a world map. A histogram at the bottom displays the total dead and missing by month, with a brushable time range that dynamically filters the bubbles on the map above. Built with React, it uses D3’s `geoNaturalEarth1` projection, `scaleSqrt` for bubble sizing, and `brushX` for range selection. Data comes from the Missing Migrants Global dataset; country boundaries use the world-atlas TopoJSON.
