You could do a Poisson limit graphic. The result is at http://en.wikipedia.org/wiki/Poisson_limit_theorem http://en.wikipedia.org/wiki/Poisson_limit_theorem

You could do a Poisson limit graphic. The result is at http://en.wikipedia.org/wiki/Poisson_limit_theorem http://en.wikipedia.org/wiki/Poisson_limit_theorem Basically, you need a whole lot of events which occur in an essentially independent way, and each one is rare. You add up the number of events that happened, and it is approximately Poisson. Something like tossing 1000 marbles into a 100x100 tile floor, and counting the number of marbles that landed in some 10x10 tile area.
