Leon is a designer working on a custom donut making app. At the moment he is drawing on a piece of paper labeled $$Donut Creation$,$ and has already drawn several rectangles on it$.$ The first rectangle shows a home screen with a navigation bar leading to different areas like $$Create$,$View$,$ and $$Settings$.$ A second rectangle shows a very interesting looking donut with options to change $$toppings$,$icing$,$dough$,$ and more. As well as buttons that are labeled $$Accept$$ and $$Cancel$.$ An arrow connects the two rectangles from the $$Create$$ label on the first rectangle to the second rectangle. The arrow itself is annotated $$User selects Create Donut in nav bar$.$ Leon is working on a third rectangle that is connected to the second rectangle via an arrow from the $$Accept$$ button. This arrow is annotated $$User selects Accept from the button prompts$.$
