This visualization displays cities as semi-transparent points on a natural Earth projection map. The map is rendered as SVG using React, with geographic features generated via `geoNaturalEarth1`, `geoPath`, and `geoGraticule` from d3. Country landmasses are drawn from TopoJSON data loaded with `feature` and `mesh`, while city coordinates come from a CSV file processed with `csv`. The points are positioned by projecting each city's longitude and latitude through the projection function.
