This fork of a D3.js mapping tutorial displays a natural Earth projection of the world, with countries filled in light green against a blue sphere. The visualization renders as an SVG using D3 v5’s `geoPath` and `geoNaturalEarth1` projection, while the topojson library’s `feature` function extracts country boundaries from the world-atlas dataset at 110m resolution. Country paths are drawn with a semi-transparent black stroke, and the map appears static without interaction.
