Well... if you've calculated the shortest path between all pairs of nodes in a
graph.... the diameter of the graph is the distance between the two nodes that
have the longest "shortest path" isn't it.

By the way... do you have a directed or undirected graph? I don't know how
efficient the Floyd-Warshall algorithm is, however, I note that it requires
the graph to be directed.
