This example displays a static choropleth-style map of countries, rendered as gray SVG paths with dark strokes on a white background. The code uses D3 v4’s `d3.geoPath` with a `d3.geoAlbersUsa` projection, though the title suggests a country map. It loads TopoJSON data from a remote gist via `d3.json`, then applies `topojson.feature` to extract country geometries. The map is positioned within an SVG using margin-based translation, styled with CSS from an external stylesheet.
