Hi Jason,

How does this compare with fgl? http://hackage.haskell.org/package/fgl

A couple of months ago, I was working on a project where I had to do some graph analysis. I encountered two problems with the fgl library: (1) The fgl library did not work for large graphs, even graph construction would fail with stack overflow. (2) The fgl library did not provide the graph algorithms needed in the project: closeness centrality, Brandes betweenness centrality, eigenvector centrality, pagerank and some more. The igraph library featured all functions that I needed and also worked for large graphs without problems. I was also very pleased with its performance and started writing Haskell bindings to igraph. Cheers, George
