But usually it is a handful of really large contributors and more smaller ones. And that's fine, but I'm not aware of a project where the contribution graph is more or less flat. And more often than not those large contributors are paid by large companies to contribute.

I wonder which largish FOSS project has the flattest contribution graph?

That's a great question. Whichever project it turns out to be their governance and leadership will be well worth studying.
