This example demonstrates how to load and display world map data using D3.js and TopoJSON. The visualization fetches country boundaries from the world-atlas dataset and projects them as SVG paths. The code uses `d3.json` to retrieve the TopoJSON file, `topojson.feature` to convert it into GeoJSON, and `d3.select` to append the resulting shapes to the chart. The map is rendered as static SVG elements within a fixed 960×500 viewport.
