Immoral seems to be a bit of a strong word here. But then I don't use git/github much.

Can you explain?

The parent post mentioned "moral", I was just making the point not to take online infographics too seriously - there are inaccuracies in both directions.

It'll display correctly once you merge your non-master branches down.

doesn't seem to be working for me.

complete stab in the dark here, but perhaps however you're getting your work onto master is rewriting timestamps (NFI if the graph goes off authored or commited dates).

Maybe try 'git checkout master && git merge --no-ff feature-branch' and see if that helps
