This example displays a world map using D3.js, loading geographic data from the World Atlas TopoJSON file. The code uses `d3.json` to fetch the dataset and `topojson.feature` to convert it to GeoJSON for rendering. The SVG canvas is set to 960 by 500 pixels, with the map drawn using the `d3.geoPath` projection system. The example demonstrates the basic pipeline of loading, parsing, and visualizing geographic data in the browser with SVG output.
