My guess was that it was going to be the container library, rather than the language itself. If libraries are included, then Clojure-inspired HAMTs are in Haskell as well. But really, Clojure, Haskell and Scala are all just implementing Bagwell's ideas, http://lampwww.epfl.ch/papers/idealhashtrees.pdf whose feasibility was shown in Clojure.

See e.g. for Haskell, originally as http://www.haskell.org/pipermail/haskell-cafe/2010-February/... and now as http://www.haskell.org/wikiupload/6/65/HIW2011-Talk-Tibell.p...

However, your graph will be much more complicated if libraries are allowed to influence each other, rather than strictly considering language features.

This walks a thin line for sure and in Scala the line is almost microscopic. I'll keep it for now since my reasoning was the same as the Erlang->Scala influence. A core language library that is rarely viewed as other than a core feature.

I disagree with that. There is great attention between language features and functionality shipped in the standard library. This http://clojure.com/blog/2012/04/19/take5-daniel-spiewak.html might also be of interest.
