Given Pingu's description of the nature of his problem (trying to motivate choice of one criterion to use), this may well be all that is necessary. Simple pictures often have the advantage of being readily understood. I'll second this advice, with the comment that you need to be careful not to summarise out the potential problems mentioned by the other posters, at least until you have checked for their presence. (For example, avoid using a display that hides a learning effect unless there isn't one.)
