Visualize branches on GitHub

In TortoiseGit, gitk or on BitBucket, it is common to have a visualization of the project history with all the branches, like this:

However, GitHub's commit history seems to be flat, at least I couldn't find a way to display this kind of graph. Can the GitHub's web UI somehow visualize branches like other Git clients commonly can?

You can see a graph, but without commit messages in Insights => Network section (commit messages with authors are shown on hover).

Note: this works for public repos or GitHub Enterprise only!
