[instaviz-users] Rotated squares aren't diamonds?

[Michael C. Mancini]

I tried this same test with my parents. I told them they could draw a  
diamond shape, but did not tell them how. They drew it as a 45 degree  
square, with the same results as your mother.

I think the correct behavior would be to accept a 45 degree square as  
a diamond, since this best reflects user intent.
