CSE512 Data Visualization (Spring 2024)

The world is awash with increasing amounts of data, and we must keep afloat with our relatively constant perceptual and cognitive abilities. Visualization provides one means of combating information overload, as a well-designed visual encoding can supplant cognitive calculations with simpler perceptual inferences and improve comprehension, memory, and decision making. Furthermore, visual representations may help engage more diverse audiences in the process of analytic thinking.

In this course we will study techniques for creating effective visualizations based on principles from graphic design, perceptual psychology, and cognitive science. The course is targeted both towards students interested in using visualization in their own work, as well as students interested in building better visualization tools and systems.

In addition to class discussions, students will complete visualization design and data analysis assignments, as well as a final project. Students will share the results of their final project as both an interactive website and a video presentation.

Activities, Learning Assessments & Expectations for Students

Important Announcements: We will send all course announcements through Ed, including corresponding emails. You should make sure that you do not miss these messages. You are responsible for checking your email and Ed with regular frequency.

Readings: To contribute to lively and insightful discussions, we each need to do our part to be prepared. Students are expected to complete assigned readings prior to lecture. All readings are listed in the course schedule.

Lectures & In-Class Activities: It is important to attend lectures and read the readings. In class we will assume that you have read the day's readings and are ready to engage in the day's activities. In-class lectures will be in person and recorded. Poll Everywhere will be used for audience activities and to track attendance. For in-class activity days, lectures will be pre-recorded and shared ahead of time. Students may miss two lectures and two activity days without penalty to their course participation grade. In addition, students may have excused absences due to illness, work-related travel, or other issues; please reach out to the instructor as needed.

Quizzes: We will post short quizzes to reinforce important concepts. Quizzes are included as part of course participation and can be submited as many times as you need to get all questions correct.

Assignments: There will be three assignments to help prepare you for the final project. These assignments are designed to give students experience in creating and evaluating visualization tools. See the course calendar for assignment dates.

Final Project: A team-based (1-4 person) final project is due at the end of the course, with periodic milestones. The goal of the final project is to identify a new, interesting and challenging visualization problem, and to apply the techniques and skills learned in class to address this problem. Students are welcome to work on their own research or final project ideas for the course.

Please feel free to reach out about personal, academic, or intellectual concerns. However, please consult the syllabus and Canvas first for logistical questions, such as when an assignment is due or how much an assignment is worth in terms of grading.

Policies

Late Policy: You have two (2) total late days that you can apply as needed to turn in an individual assignment (A1, A2, Peer Reviews) after the due date without penalty. For example, you can submit A1 and A2 one day late, or submit just the A2 peer review two days late. Each project team also has an additional late day for A3. No late days are given for final project milestones. Beyond late days, we will deduct 10% for each day an assignment is late. Please contact the instructors on Ed Discussion prior to a deadline if you intend to apply your late days or if you would like to request additional accommodations.

Plagiarism Policy: Assignments should consist primarily of original work. Building off of others' work—including 3rd party libraries, public source code examples, and design ideas—is acceptable and in most cases encouraged. However, failure to cite such sources will result in score deductions proportional to the severity of the oversight.

Religious Accommodation: Washington state law requires that UW develop a policy for accommodation of student absences or significant hardship due to reasons of faith or conscience, or for organized religious activities. The UW's policy, including more information about how to request an accommodation, is available here: Religious Accommodations Policy. Accommodations must be requested within the first two weeks of this course using the Religious Accommodations Request form.
