This example displays a choropleth-style map of Russia, with each state filled in red and outlined in black, rendered as SVG paths on a bisque-colored background. The visualization uses D3’s `geoPath` with the `geoNaturalEarth1` projection, centered on Russia, and loads TopoJSON data via `topojson.feature` to draw regional boundaries. Users can pan and zoom the map using D3’s `zoom` behavior. An ordinal color scale (`scaleOrdinal` with `schemeCategory10`) is defined, though only the red fill is currently applied.
