This interactive data visualization combines a geographic bubble map with a time-series histogram, allowing users to explore migrant deaths by location and date. The map projects the world using the Natural Earth projection, with circle sizes proportional to the square-root-scaled death counts, while the histogram bins reported dates by month and supports brushing to filter the map's data. Built with React and D3 v5, the visualization uses `d3.geoPath`, `d3.scaleSqrt`, `d3.scaleTime`, and `d3.brushX` to render SVG marks. Data comes from the Missing Migrants Global 2019 subset, with country boundaries from the world-atlas TopoJSON.
