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
- Instead of one picture with 3 diagrams, three separate pictures would be more useful. Perhaps with circles of different sizes (and the forumla above or below the diagrams. In addition,
- a diagram for and (perhaps) also for the relative complement
- in the same graphical design would be useful.
