There is a current proposal to add a graph library to the C++ standard library. Targetted at C++26 or later. Since this community is very accostumed to working with graphs, I thought that it would be interesting to share this here.
Their code is in the repos source library and stdlib. IMHO, the interface could be improved a lot. At least it does not match what I tend to use for competitive programming and it seems quite far from the std::algorithm interface. I hope to hear your thoughts.
