Hi MO,

My nodeeditor has the wrong node, infos>Display
Where is the latest Display node? I have Jame's Sept 14, 2020 nodeeditor version. Is it still the latest?

Also, I do not have the "Blue/Green/Teal" nodes which have one input, and have Title, Style, and Edges, where the Title serves as a label.
Where is a copy of this node located?

After replacing Display node, and removing the several "label" nodes, your script ran.
Your Radius shows as 0.9293, for Scale X = 1
The length of your 4 unit chords are different, and do not equal 1 unit.
zooming way in shows top and left points slightly outside of the circle.

-Thankyou
