There are some graph families here:
http://cs.anu.edu.au/~bdm/data/
http://www.cs.uwa.edu.au/~gordon/data.html
However, we do not attempt to list elementary properties. It would
be nice to have the type of intelligent database you describe, but I
don't know if you will be able to add enough properties to satisfy
many requests. People have a vast array of different ideas about
which graphs are interesting. Some rare properties, for example
Ramsey properties, high girth, or strong connectivity, need special
programs for their efficient generation.
