Monotone Symmetric Venn diagrams
without polar symmetry
There are 17 of them, which we call M1M17.
Clicking on those numbered M12M17 return
Tutte a embedding of the diagram.

M1.
This one has the zigzag middletwolevels and the rather nice property
that each curve interects the others exactly 6 times. It was
discovered by Carla Savage and Peter Winkler.

This one was discovered by Branko Grünbaum (Figure 6 of
[Br92b]),

The numbers above are simply the order in which our program
found them.
We have seen none of these published before, except for M1 and M2.
