    It would be so much better to either have the grade distribution graphs hidden as the default so that teachers have to go in and turn it on.   There are student privacy issues at stake.   If not, being able to turn it off at the account level would also work.  For teachers that teach many courses, remembering to do this for every single class, especially since it is a hidden option is very tedious.
