Where can I find graphs relevant to real-life problems?
Two repositories I know of are:
- University of Florida's Sparse Matrix Collection
- Bodlaender's TreewidthLib

$\begingroup$ similar, I think synthetically generated graphs should go there $\endgroup$ – Yaroslav Bulatov Dec 1 '10 at 5:16

1$\begingroup$ Nitpick: It should be Bodlaender. $\endgroup$ – gphilip Dec 1 '10 at 20:18

1$\begingroup$ There are some large graphs from real-life, in DIMACS Benchmarks for Shortest Path Problem: dis.uniroma1.it/~challenge9/download.shtml#benchmark $\endgroup$ – Arman Feb 23 '11 at 21:17

The UCI Network Data Repository has a collection of social networks, with additional attributes (not just vertices and edges). They also have a set of links to similar collections elsewhere.

I found the following two sources useful to analyze my betweenness centrality algorithms. These are more biased towards being "social". You will find more data by searching "protein interaction networks" on google.
- SNAP at Stanford
- Graph Datasets at Washington State University

There are some real benchmark instances for Frequency Assignment problem on: http://fap.zib.de/problems/

The comments have some good data sets. There's also some Facebook data here.
SNAP has some interesting data

You might try checking this page on data sets from the "International network for social network analysis":
http://www.insna.org/software/data.html
If you have access to either "Networks, Crowds, and Markets" (Easley and Kleinberg, 2010) or "Social and Economic Networks" (Jackson, 2008), they're both full of references to datasets in the literature.
Edit: You can find a pre-publication draft of Networks, Crowds, and Markets at:
http://www.cs.cornell.edu/home/kleinber/networks-book/
Chapter 2 contains a section called "Network Datasets" that might give you some ideas.

- SNDlib has a collection of instances for survivable network design.
- A collection of large road networks is available on the page of the 9th DIMACS implementation challenge.
