This visualization of student interest data is based on the methods of MatrixWave and Radial Sets to reveal the complex nature of transfer patterns between majors from pre-college to sophomore year. 18 nodes in matrix view and sets in radial view represent the college majors. Rectangles in matrix and arcs in radial set represent outflux of students colored red, influx of students colored blue. Views use diagonal rectangles colored grey in matrix and grey sets in radial set as the follow-through students. The adjacent Matrix views aim to visualize the transfer among different majors spread out three matrix years. Radial sets emphasize the variations between years with ranking, taking a circle overview as a college. To explore Perceived vs. Actual Student Interest, we can strength the most relevant majors and highlight the main features to find out pattern in these students’ data, with two views together.
