This visualization maps events from the Missing Migrants Dataset as circles sized by the total dead and missing per incident. It uses a natural Earth projection with SVG rendering, showing country boundaries, graticules, and a sphere outline. The code leverages d3.geoNaturalEarth1, d3.geoPath, and d3.geoGraticule for map geometry, while d3.scaleSqrt maps death tolls to circle radii. Data loading relies on d3.csv and topojson for world atlas features, all within a React framework using d3.v5.
