I’ve just got a tiny url from a friend ( click ) and this shows that Wolfram Alpha can also plot complex functions in a very nice way. All this is pretty amazing and I just found out that there are ton’s of examples how they process data ~ either by plotting mathematical things, calculation chemical stuff, doing string-analyses or plotting fractals :)

Btw - google looses on all of these queries :P (1) (2) (3) (4) (5)
