This map visualizes missing migrant incidents worldwide, with each circle positioned at the incident’s coordinates and sized by the total number of dead and missing. It uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`, rendering landmasses, graticules, and interiors from the World Atlas TopoJSON. Circles scale with `scaleSqrt` based on the CSV data, while React manages state and rendering.
