[post author] You are right. Any "language" visual or other wise used for communication has to include the level of detail trying to be communicated. In the Rust memory layout example, Rust syntax doesn't spell out its memory layout in Rc<T> definitions.

The point though is that the two users of the language _decide_ to communicate in a visual representation! Why is that?

They could spell it out in text, adding that lower level to the text, and yet they don't. That is a sign the users are thinking about it visually and the visual representation maps better to what they hold in their head.
