Horizontal vs Vertical Internal Regions in State Diagrams

General Questions/Discussions

What is the difference between a Vertical and a Horizontal region in a state digram state component?
What I do know is that an internal region is to show a non state change but some internal change that doesn’t result in a state change (non-self transition).

Thanks!
