This example demonstrates how to build a world map using D3.js, rendering geographic features as SVG paths with a natural Earth projection. The visualization loads geographic data from an external JSON file and uses the TopoJSON library to parse it before drawing each country or region. D3’s `geoNaturalEarth1` projection defines the map’s perspective, while `geoPath` projects the coordinates onto the screen. The code relies on D3 v5’s `json` method to fetch the data and uses `.enter()` to append the paths, offering a straightforward template for creating choropleth or point-based maps.
