This map displays European and North African cities as dark dots on a light landmass, with each city labeled by name. The visualization uses D3.js v5 to load geographic data from a GeoJSON file and city coordinates from a CSV file. It renders the map by applying the Mercator projection through `d3.geoMercator` and drawing paths with `d3.geoPath`, while circles and text elements are positioned using the same projection function.
