A React-based world map displays migrant deaths and missing persons as semi-transparent circles, sized using a square-root scale to encode the reported total per location. The natural Earth projection renders geographic landmasses and graticules via `d3.geoPath`, with topojson world-atlas data providing country boundaries. Circle positions derive from parsed CSV coordinates, while hover tooltips reveal the reported date and death count. The visualization uses `d3.scaleSqrt` for radius mapping and processes data through custom React hooks for asynchronous loading of both map and migrant datasets.
