A world map visualizes the global distribution of women in parliament, with each circle representing a country and its radius scaled to the percentage of parliamentary seats held by women. The visualization uses a natural Earth projection via `geoNaturalEarth1` and `geoPath` to render landmasses, graticules, and country boundaries from World Atlas TopoJSON. Semi-transparent circles are plotted using `d3.scaleSqrt` to encode the data, which is loaded from a CSV file, over a React-based SVG rendering.
