Sorry about that. Beyond my control -- this LucidChart tool is just
something free I found. Perhaps I will have to redo it in LibreOffice
or the like.

Well, yes, but they were not Wirth projects, or at least not Wirth-led
or Wirth on his own. They are also very well-known,
widely-influential, and the ancestor of so many other languages from
Basic to C that to include all the offspring of Algol would include
almost every programming language there is except Lisp and Fortran.

That is why I chose to exclude them. Does that seem fair?
