This example displays a world map rendered as an SVG using a Natural Earth projection. The code loads GeoJSON data from an external GitHub repository and draws each country as a filled path with a white stroke, using the `d3.geoPath` API. The visualization is built with D3.js v4, specifically employing `d3.geoNaturalEarth1` for the projection and `d3.json` for asynchronous data loading.
