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

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: It is important to attend the lectures and read the readings. Each lecture will assume that you have read and are ready to discuss the day's readings. This quarter, all lectures will be in person and recorded. If you speak during a lecture, you will be included in the video. Keep this in mind as you attend the lectures!

Discussion Posts: Class participation includes both in-lecture activities (as is feasible) and engagement on the course discussion site (Ed). All enrolled students are required to submit at least 1 substantive discussion post per week related to the course readings or lecture material. Each student also has 1 pass for skipping comments.

Good comments typically exhibit one or more of the following:

• Critiques of arguments made in the papers
• Analysis of implications or future directions for work discussed in lecture or readings
• Clarification of some point or detail presented in the class
• Insightful questions about the readings or answers to other people's questions
• Links to web resources or examples that pertain to a lecture or reading

Quizzes: We will post short quizzes to reinforce important concepts. Quizzes are considered a part of course participation and are not graded (your score on a quiz will not affect your course grade).

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 final project is due at the end of the course, with periodic milestones throughout the quarter. 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 final project ideas for the course, but a list of potential final projects will also be shared. Check the course calendar for final project milestone deadlines.

Commitment to Fostering an Inclusive Learning Environment

This course welcomes all students of all backgrounds. The computer science and computer engineering industries have a significant lack of diversity. This is due to a lack of sufficient past efforts by the field toward even greater diversity, equity, and inclusion. The Allen School seeks to create a more diverse, inclusive, and equitable environment for our community and our field. You should expect and demand to be treated by your classmates and the course staff with respect. If any incident occurs that challenges this commitment to a supportive, diverse, inclusive, and equitable environment, please let the instructor know so the issue can be addressed.

Policies

Late Policy: We will deduct 10% for each day an assignment is late. Please contact the instructors well in advance to request extensions if needed.

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.

Excused Absences: Students are expected to attend class and to participate in all graded activities, including midterms and final examinations. A student who is anticipating being absent from class due to a Religious Accommodation activity needs to complete the Religious Accommodations request process by the second Friday of the quarter. Students who anticipate missing class due to attendance at academic conferences or field trips, or participation in university-sponsored activities should provide a written notice to the instructor ahead of the absence. The instructor will determine if the graded activity or exam can be rescheduled or if there is equivalent work that can be done as an equivalent, as determined by the instructor.

Medical Excuse Notes: Students are expected to attend class and to participate in all graded activities, including midterms and final examinations. To protect student privacy and the integrity of the academic experience, students will not be required to provide a medical excuse note to justify an absence from class due to illness. A student absent from any graded class activity or examination due to illness must request, in writing, to take a rescheduled examination or perform work judged by the instructor to be the equivalent. Students are responsible for taking any number of examinations for which they are scheduled on a given day and may not request an adjustment for this reason alone.

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.

Q&A

Canvas & Ed Discussion: The class will be managed from Canvas and Ed Discussion. If you need to reach out and communicate with course staff, please post on Ed Discussion or send an email to the course staff. You are likely to receive a faster response from us if you post questions, comments, and concerns directly through Ed Discussion. If you have a private question, please email the instructors at cse512@cs or discuss it at office hours.

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

Important Announcements: We will send all important 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.
