Workflow diagram

I’ve been searching unsuccesfully for a diagram that documents the WooCommerce workflow. We’re starting to work on creating one, but it would be most helpful if someone has done this already. Ideally, including state diagrams etc to UML2, but more than happy to see whatever exists. Does anyone have anything, or know where it might be available?

I’ve found this diagram which is applicable to subscription renewals;
https://docs.woocommerce.com/wp-content/uploads/2013/07/subscription-renewal-process-flow-chart.jpg

Something like this for the add to cart, checkout, payment (including failed payment), order processed workflow is what I’m after.

Thanks in advance
