This example visualizes the Missing Migrants Dataset, where each circle represents a single recorded event and its radius encodes the total number of dead and missing. The map uses a Natural Earth projection rendered with `d3.geoPath`, while country boundaries come from the world-atlas TopoJSON file. The visualization is built in React, with size scaling handled by `d3.scaleSqrt` and data loading through `d3.csv`. Each point is drawn as an SVG circle with a semi-transparent fill.
