Where does it show the branches and merges?

It’s weird if GitHub doesn’t have that. Gitlab does. https://gitlab.com/gitlab-org/gitlab-runner/-/network/main

That would be the network view.

that only shows you inter-repository activity, not the branches within a repo.

that would be worthless for most people, and for the sqlite authors, who'd surely have a million people pressing the 'fork' button.

it also isn't what anyone in the thread, or post, were asking for.

all i've ever seen is something which displays a single branch, and does not contain the graph structure information present in git log --graph.

perhaps you'd be so kind as to provide a link to a page on github which demonstrates the same graph structure?

I’ve never found that either. I try to limit my interactions with GitHub to copying the URL to clone and doing pull requests. GitHub has the same relationship to Git as OverLeaf has to LaTeX: a layer of excrement smeared over and defacing a beautiful program. The saddest thing is that much of the current generation of programmers think that GitHub is Git.
