Another interesting visual technique is given by the
qreference() function in pkg:DAAG. I've used this type
of display effectively with non-stats people as well
as in teaching intro courses in stats.
(I would randomize the location of the actual-data panel
and not use a different colour. The question then is,
can you discern the actual data from the simulated data?)
