phrase needed

[Lori A. Schwabenbauer, Camden County Library]

There was something called a Venn diagram, but it was more visual - involved
drawing intersecting circles and shading in the area you were searching for:
A+B but not just A or B (just the overlapping part would be shaded), A or B 
(the whole of the 2 circles would be shaded), and so forth.
