This example presents a world map rendered as an SVG using a Natural Earth projection. It displays country boundaries as red paths with a subtle maroon stroke, set against a yellow sphere backdrop. The visualization loads GeoJSON data from a remote gist, processes it with `topojson.feature`, and draws the map using `d3.geoPath` and `d3.geoNaturalEarth1`. The code leverages d3.v5’s `json` method for data fetching and `select` for DOM manipulation.
