This example visualizes missing migrant incidents on a world map, with each circle’s radius proportional to the total number of dead and missing individuals at that location. The map uses the natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`, with land, graticules, and country interiors rendered from World Atlas TopoJSON data. Circle sizes are scaled using `d3.scaleSqrt`. The React app loads CSV data from a static gist and renders the visualization with SVG, overlaying semi-transparent teal circles on a gray map.
