Thanks for your answer.
I know the dot package, actually wrote my master thesis using it, but
as you said, its not a php solution. :(
To anticipate the next answer in this thread: I know about cgi etc,
but I do not have any rights on the server this is supposed to run, so
i search a PURE php solution.
