Here we have a graphic about popularity of UFCG computer science course flowchart. Each box is a semester and each circle is a graduated student in a specific semester (from her/his first to her/his last semester). The y axis corresponds to the number of courses (he/she did at this i-th semester) that correspond to the indicated at the flowchart. If you select some students (circles) at a box, they will be also selected at the rest of boxes, so you can see how a specific student (or a group of students) followed what the course flowchart indicates.
