Graph creation and access

Online built graphs or imported graphs can be private or public on the owner's decision.

Public graph copy

Public graphs can be copied; the copy then belongs to the one who duplicated.
A public graph can become a private one, but it could have been duplicated while public. This copy is under the public graph terms of service while the original is under the private graph terms of use.

Deleting graphs

If a user deletes his user account, he can delete his private graphs but not public ones.
