This example visualizes a world map by loading geographic data from the world-atlas TopoJSON file and rendering country boundaries as SVG paths using `d3.geoPath` and `geoMercator`. The code imports `select`, `json`, and `geoPath` from D3 v5, along with `feature` from TopoJSON to convert the TopoJSON topology into GeoJSON features. The map is drawn inside an SVG canvas with a width of 960 pixels and height of 500 pixels, though the visible output is limited to the console log of the parsed data.
