This visualization maps the global distribution of missing migrants, with circle size encoding the total number of dead and missing per reported location. The map uses a natural Earth projection via `geoNaturalEarth1` and renders geographic features with `d3.geoPath`, including land masses, graticules, and interiors. The React app loads CSV data from a GitHub gist using D3’s `csv` parser, while world topology comes from the world-atlas package. The size scale uses `scaleSqrt` to map values to circle radii, and SVG circles are positioned using the projection’s coordinate output.
