+<strong>Reading the graph:</strong> each polygon contains a revision. The hexagon represents this revision, and arcs 
+represent ancestry. An arc from revision A to revision B indicates that revision A is an ancestor of revision B. 
+Arcs that do not connect to a node are connected to a node that was not drawn for space reasons. Any node should be 
+clickable, and will take you to that node's revision page.
