As one of my better bosses used to say:

    Graphs are for asking better questions, not for making decisions.

When I use graphs to brainstorm ways to verify the existence of a problem, I have a lot better time than when we jump to conclusions. There's something a little rotten in pretty much any projection of data that you try. Building policy off of a graph is a bad, bad plan.

Such a bad plan in fact that Mark Twain has a joke about it.
