A Page Graph can show not just pages that are pointed to, but also pages that *those* pages point to.
See Step-By-Step Page Graph for the table of contents.
--- Making a two-level graph for this page produces a graph with an overly-complicated structure (but you can look at it below). So for this explanation I've made a simpler structure at Example Page 1. The explanation continues there.
