This fork of the “Let’s make a map with D3.js!” example renders a world map using an SVG canvas with a natural Earth projection. It uses `d3.geoPath` and `d3.geoNaturalEarth1` to project and draw country boundaries from TopoJSON data loaded via `topojson.feature`. The map displays a blue sphere outline and light green countries with thin black strokes, based on the world-atlas 110m dataset. The code loads D3 v5 and TopoJSON v3 from unpkg, with styling applied via an external CSS file.
