Though the obvious method of creating a Venn Diagram is a bit disappointing,
you can use the Fragment commad for a better effect.
Obvious - Create three circles and use transparency to blend the overlapping
colours. The result is muddy.
Fragment - Create three circles, overlap them, select them all and then
choose Fragment from the Operations command of the Shape menu. This will
create a set of shapes that represent the various overlap situations and can
be coloured independantly.
