I once saw a diagram that gave the genealogy of the lisp family of languages.
I remember it from some years ago, but was impressed with how many different
dialects there were and how many strains of development were going on in
parallel.  I have looked at the McCarthy article in SIGPLAN from 1978
and everywhere else I thought I might have seen it, but cannot find it.

Has anyone done a current picture showing the genealogy of lisp?
The one I remember may have been part of a vendor's presentation,
but certainly didn't show the present threads of scheme and CL.
Perhaps one exists in a textbook or historical article somewhere.

My reason for asking is I would like to use it in a class
to convey how much effort goes into developing a mature language,
especially when there have been 30 years to think about it.

Thank you.
