Feature Description

A note that explains what the "Other" category is on the course grade description.

Proposed Solution

Figure out where those numbers come from (are they just Q-drops or something else?) and just have a small note under the grade distribution chart to let the students know what that number is (especially if the "Other" category has high numbers).

UI/UX Considerations
I think it would make sense for the note to be right below the "Instructor-specific data is not available for this course, showing course-wide data instead" note in gray.

Technical Implementation Details

I agree that we need a note explaining what "Other" is. We should make the "Other" chart label into a link similar to the "About the Data" link. When the user hovers over the label, it would open up a large tooltip with the following content: "The 'Other' grade category includes all non-standard letter grades, including: In Progress, Incomplete, Permanent Incomplete, Oblit, Q-Drop, Withdrawn, Credit, No Credit, Satisfactory, Unsatisfactory, and Registered on CR/F or CR/NC basis." In that case, we can change the "About the Data" text to "Data Source".

This issue depends on Tooltips, which is WIP by Elie. So Im adding this to backlog for now.
