d3-geomap is designed to be a reusable geographic map for D3. In its current stage it consists of a class to create plain maps d3.geomap() and one for choropleth maps d3.choropleth().

Refer to the documentation on how to use d3-geomap and to download a bundle that contains minified versions of d3-geomap and its dependencies as well as TopoJSON files for creating world and individual country maps.
