Gephi forums

I cannot find anywhere what the word "gephi" means. I assume it is an acronym or abbreviation for something, but it would be nice to know as I know what pajek means as well as UCINET. It would also help me how to pronounce gephi if I knew what the "i" meant, which would be either a long i in English or a long "e." Thank you.

It's the letter G for graph plus the symbol Phi (it's in the logo!).
