This visualization maps the global distribution of missing migrants, with circle size encoding the total dead and missing per location. The map uses a natural Earth projection rendered via `d3.geoPath`, with land, graticules, and country interiors drawn in SVG. React manages the component state, while D3 scales (`scaleSqrt`) determine circle radii. Data comes from the Missing Migrants Global 2019 subset CSV, loaded with `d3.csv`.
