Deterministic output for .dot

[XF-FW]

Hey. My workflow involves generating a dot file on every commit and diffing with the current one, to see if there are new changes.
The current dot output has two things that may differ even with the same src:

• Timestamp
• Abstract model order

Added an option for deterministic to be able to set it as a constant value and fixed the shuffling done with the abstract models, via list(set(x))
