A map of the world uses D3's geoNaturalEarth1 projection and geoPath to draw landmasses and graticules, while circles sized with a square-root scale encode totals of dead and missing migrants per location. A time-series histogram beneath the map bins the same reported data by month using d3.bin and scaleTime, with bar heights scaled by monthly fatality counts. React manages the state and rendering of both views, loading world geometry from TopoJSON and CSV data from a gist.
