This example displays a static map of Russia using a Mercator projection. The map is rendered as a single SVG path element, filled with blue and outlined in black, using the `d3.geoPath` and `d3.geoMercator` functions. Geographic data is sourced from a world atlas TopoJSON file via `d3.json`, and the specific country feature is extracted using the `topojson-client` library. The viewport is fit to the country’s bounding box with `fitSize` before drawing.
