A world map with semi-transparent blue circles marks the total dead and missing migrants at their recorded coordinates. The visualization uses a natural Earth projection via `d3.geoPath` to render landmasses and graticules, with each circle’s radius scaled by `d3.scaleSqrt` based on the data values. Data comes from the Missing Migrants Project CSV, loaded with `d3.csv`, while the map uses TopoJSON from world-atlas. React manages the component state, and SVG renders the final output.
