Most documents are already graphs of sorts. The fact that they are written down as they are is an implementation detail dictated by traditional physical constraints. I would image all authors have a "graph" in their heads before writing down the text. I'm pretty sure information are lost when this happens. I guess this is what the article tries to address.
