Nice sheet, though I have a few critiques:

Why does it say where T: Sized for references &T? A reference can definitely point to an unsized type, e.g. &str.
The yellow boxes really mean "must be heap allocated" - all the other references (&T, &[T] and &dyn Trait) may either point to the stack or the heap.
