This is related to visual programming, not flow based programming.

I modified a python hosted lisp interpreter to read JSON flavored lisp - JLISP. It's much easier to get a web frontend to output JSON then lisp. Then I made a simple Low Code UI built around this language. The editor has operations (invocations of lisp functions) organized left to right like a timeline in CAD software, then you can click on an individual operation to edit the arguments.

Here is a video walking through the system https://youtu.be/3Tf3lnuZcj8

I'll make a statically exported Jupyter notebook shortly
