A world map displays child mortality events, with each circle representing a recorded incident and its size scaled by the number of dead and missing individuals. The visualization combines a Natural Earth projection, geographic graticules, and country boundaries rendered as SVG paths. React manages the component lifecycle, while d3’s `geoNaturalEarth1`, `geoPath`, and `scaleSqrt` handle projection, path generation, and radius encoding. Data comes from a World Bank CSV file, and country shapes use the World Atlas TopoJSON dataset.
