[en] Review §3 [page 6]

It is not a word processor or text editor, but, as I said before, a system,
or in other words a suite of tools aimed at typesetting documents,
understood as the graphic layout and visualisation of the different
elements of the document on the page or on screen.

This paragraph has an ambiguous meaning or is a nonsense: when you view a document
you can actually see the whole document (e.g. image, paragraph, color, line, character, spacing...).

Moreover, I don't understand what do you mean using the expression graphic layout. What does this mean?
