I read Andrej Karpathy's A Survival Guide to a PhD and in the section titled “Get the gestalt right” he writes (about scientific papers):
Your papers, as you become a more senior researcher take on a characteristic look. An introduction of ~1 page. A ~1 page related work section with a good density of citations - not too sparse but not too crowded. A well-designed pull figure (on page 1 or 2) and system figure (on page 3) that were not made in MS Paint
I haven't hear the term pull figure before, and can't find a satisfying explanation online.
