These sorts of charts always fall short because they never explain how they were influenced. If you're not in the know already, this provides little information to you. Prolog influenced Clojure, but how? If I didn't already know about core.logic, I'd be scratching my head about why. And even then, it took me a good minute to rack my brain to think of some possible way they were connected because it's not obvious.

I dunno, I found it useful in that my favourite language (Lua) has some interesting connections I wasn't aware of before, such as the influence on Io, which is new to me.

Point is, it was sort of fun to browse around and see just how incestuous our language universe is...
