This world map visualizes the Missing Migrants Dataset, with circles sized by the total number of dead and missing individuals at each location. Using React for rendering and d3-geo-projection’s `geoNaturalEarth1` projection with `d3.geoPath`, the map layers country boundaries, graticules, and geographic lines. Circle radii scale via `d3.scaleSqrt`. The data comes from a CSV, while world atlas and line geometries are loaded from TopoJSON.
