This example demonstrates how to create a simple world map using D3.js v5 and TopoJSON. It loads geographic data from a remote JSON file and renders each country as an SVG path using `d3.geoMercator` for the projection and `d3.geoPath` to generate the path data. The map is drawn onto a static SVG canvas with no interaction or animation. The code relies on the `json` function from D3’s fetch module and the `feature` method from TopoJSON to convert the raw data into GeoJSON features.
