There is a nice page from Stanford University that provides links to several graph datasets that can be downloaded for developing and testing data mining algorithms:

It includes some social networks datasets, citation networks datasets, internet networks, wikipedia networks, and much more, etc.

Hi

Another website with various graph datasets:

http://www.eecs.wsu.edu/mgd/gdb.html

It also contains explanations about different graph format : SUBDUE, GRAPHML, etc.

Also, a synthetic graph generator, based on the IBM Quest Synthetic Data Generation Code for Associations and Sequential Patterns

http://www.cse.ust.hk/graphgen/

It can create labeled, undirected and connected graphs.

Hello sir/maddam;
Could you please send me a graph & related dataset. I have a project in university about graphmining and i should be solve it with three methods of datamining such as Classification, Clustering, Regression, Sequential patterns, Time series analysis, Association rules.
Could you please guide me?
Best regards.
