Who told you parents are essential?  Probably your parents... :-)

I guess setting parents is good practice, but it's not essential.

does it implicitly.

Attached is what I get when I select / Ctrl-B run the first part of the
example, then add a Turtle pane, then select / Ctrl-B run the second
half of the example.

So it's visible and works.  But if your goal's drawing trees in a
QGraphicsScene I don't think you need to create a QGraphicsView of the
scene using free_layout in the first instance, that can always be done
