Note that Data.Graph is different to Data.Graph.Inductive:

module Data.Graph:
    -- A version of the graph algorithms described in:
    --
    --   /Lazy Depth-First Search and Linear Graph Algorithms in Haskell/,
    --   by David King and John Launchbury.

module Data.Graph.Inductive:
    --  Inductive.hs -- Functional Graph Library  
    --
    --  (c) 1999-2005 by Martin Erwig [see file COPYRIGHT]

The first lives in package `base', the second in package `fgl'.
