This example visualizes global migrant deaths by plotting circles on a natural Earth projection map. Each circle’s radius is scaled to the reported number of fatalities, using a square-root scale for proportional sizing. The map displays landmasses, graticules, and country interiors via `d3.geoPath` and `d3.geoNaturalEarth1`, while React components render SVG circles and axes. Data is loaded from a CSV file, and the world atlas comes from TopoJSON, with styling controlled by CSS classes.
