is it possible to make a venn diagram wherein the elements are infinite elements?

ex. V = { is the set of all odd numbers)
W = { 5, 15, 25, 45, 55,...}

thanks a lot

I have never seen it done.

All sets are infinite? The circles in a Venn diagram can denote finite or infinite sets. The circles show how the sets are related. In this case, it seems that W is a subset of V.

I agree that Venn himself used the diagrams for logical arguments.
But the OP said "the elements are infinite elements". I take that to mean some sort of counting.
Have you seem Venn's diagrams used for counting non-finite sets?
