This visualization displays a world map with blue dots marking the locations of universities from a CSV dataset, with each dot positioned at the centroid of its corresponding country. The map is rendered using D3's `geoNaturalEarth1` projection, `geoPath` for drawing country boundaries, and `geoGraticule` for the graticule overlay. University coordinates are computed by matching each school's country to its country feature's centroid via `geoCentroid`. The code fetches world atlas GeoJSON data and demonstrates an interactive React-based workflow with state management for loading data asynchronously.
