In July 2016, the University of Illinois responded to a Freedom of Information Act request (FOIA #16-456, and later #17-042) for "the grade distributions by percent and/or letter grade, for every class [...] at the University of Illinois at Urbana-Champaign". A total of 4,213 pages were released, containing the breakdown of GPA for every course at The University of Illinois. As noted in the FOIA response, some data was withheld to maintain FERPA compliance.

CS 205: Data Driven Discovery is a project-based course offered to non-CS majors by the department of Computer Science. As the first project, teams of students explored this dataset. The page is the result of the work of one team of students' work on this GPA dataset, using data from Fall 2014 through Fall 2016.

The worse the GPA, the more purple hue we add to the color.
The larger the course, the larger the radius of the circle.
