Title: Grade Distribution Graph fix

Fix for issue #657. The problem was bad data input for the graph library. It would return a list if there was no grade information, and a json list (in string format as json wont to be). This change makes it always return a json string, and uses that string as data input directly with no processing.

Unfortunately, since releasing marks doesn't seem to work right now I can't test how it looks like with a real distribution of data.
