I noticed the documentation for the distance_graph function, and I wanted to view its source code. However, when I tried to run ? graphs.distance_graph, it didn't work.

So, I searched for it on Sage's GitHub repository. I came across this line: :meth:sage.graphs.generic_graph.distance_graph for diameter distance. However, I still couldn't find the relevant description in the file sage.graphs.generic_graph. Or running ? graphs.generic_graph.distance_graph also does not work.

How can I locate its implementation?

That hardcoded reference in the documentation seems to be outdated. The following work:

sage: sage.graphs.graph.Graph.distance_graph??
sage: Graph.distance_graph??
sage: G = Graph([(0,1)])
sage: G.distance_graph??

To find the file/module:

sage: search_src("distance_graph")

Oops !! sorry. Thank you @rburing.
