comment Using GraphData to generate all directed graphs with n vertices
A generalization of your method for labeling: graphs[n_] := Module[{c, cb}, c = GraphData["Connected", n]; cb = GraphData[#, "EdgeRules"] & /@ c; Row[Column[GraphData[#, {"StandardName", "Image"}]] & /@ c, Spacer[10]]]

comment Finding a “not-shortest” path between two vertices
My goodness, this really does work. I never used FindPath and am curious to get a sense of how it works.

comment Can Mathematica Handle Open Intervals? Interval complements?
I used Mathematica v.9 (or v. 8). I must have drawn everything "by hand". If I were to do it with v.10, I would use NumberLinePlot[{{-\[Infinity] < x < -2, -1 < x <= 1, 4 < x <= Pi^2}}, x] and so forth.

Why not simply use Join?
