With these, Mathematica, and Combinatorica, most of that is possible.
http://mathworld.wolfram.com/GraphTheory.html and other pages
discuss graph theory extensively.

Eric provides graphs up to 9 vertices.

There are 1006700565 11-vertex simple connected graphs.  I don't
see a way to make a nice database for all of those.
