Rims

I agree that it is good to make it clear what the role of the rims is in these visualizations, but I don't think rectangular cuts are the way to go. --Daniel Mietchen 02:39, 10 July 2011 (UTC)

If you are talking about the rectangular "universal" set then I agree: It is irrelevant and should therefore be omitted.

If the boundaries are used to identify the "red" and the "blue" set then the complete coloured circles have to be present in all diagrams.

For my taste the boundaries are much too thick -- they should be only thick enough to clearly show their colours.

In the formulas, the symbols for the binary operations are too big. Compare

$A\cap B,A\cup B,A\setminus B$

Instead of one picture with 3 diagrams, three separate pictures would be more useful. Perhaps with circles of different size (and the forumla as abover or below. In addition,

a diagram for $A\subset B$ and (perhaps) also for the relative complement $\complement _{B}A$

in the same graphical design would be useful.
