This example displays a world map rendered as an SVG using D3.js and the Natural Earth projection. It loads GeoJSON data from a local file and draws each country as a path with a light gray fill and white borders. The code uses `d3.geoNaturalEarth1` for projection, `d3.geoPath` to generate the paths, and `d3.json` to fetch the `world.geojson` data file.
