This map visualizes the locations of cities as semi-transparent teal points overlaid on a world map rendered with a Natural Earth projection. The landmasses are filled with a light gray, while graticules and country interiors are drawn with subtle strokes. Built with React and D3, the example uses `geoNaturalEarth1` for projection, `geoPath` for geographic shapes, and `geoGraticule` for the grid. City data is loaded from a CSV, and world geography comes from a TopoJSON source, with points positioned using the projection function.
