There actually used to be some. We've moved away from them, I believe,
because of the difficulty of maintenance; which stems mainly from the
lack of any universally-available tools. Unless you can tell me what
you're going to draw the diagram with and how people on Unix, Windows,
or Mac could modify it later, I'm going to not be very interested ...
