Description of Course

The is a graduate level course on theory, design, application, and implementation of data visualizations. Students will learn principles and skills for designing, programming, and evaluating data visualizations and demonstrate these skills through coursework. Students will also learn about the research aspects of visualization. Topics include: systems architecture, algorithms, data structures, verification, and software engineering techniques for implementing and managing data visualizations; common classes of data and visual representations; methods of design and evaluation; and capabilities and limits of humans and their effect on design and implementation.

Good data visualization involves a combination of perceptual psychology, mathematics, and computer science. This makes our subject uniquely challenging: sometimes the way our eyes work stands in way of applying some beautiful result from computer science. Sometimes it’s the other way around: something deep about the math in the data will help guide the design process and let us make a picture that is beautiful, informative, and truthful.

Official Catalogue Description

Data visualization is a research area that focuses on the use of visualization techniques to help people understand and analyze data. Visualization allows us to perceive relationships, patterns, and trends. While statistical techniques may determine correlations among the data, visualization helps us frame what questions to ask. Providing efficient and effective data visualization is a difficult challenge in many real world examples. One challenge lies in developing algorithmically efficient methods to visualize large and complex data sets. Another challenge is to develop effective visualizations that make the underlying patterns and trends easy to see. Even tougher is the challenge of providing interactive access, analysis, and filtering. All of these tasks become still more difficult with the size of the data sets arising in modern applications.

This course will explore current research problems in visualizing large and complex data such as social networks with hundreds of thousands of participants and millions of relationships. Modeling such data and developing effective visualization tools is a challenging theoretical and practical task. This course will focus on classical as well as modern methods through projects that utilize real world large datasets from Netflix, IMDB, DBLP, and the Tree of Life.

Course Prerequisites

No specific courses are prerequisite, but students enrolled in this course are expected to have a foundation in computer science and be able to pick up new programming languages as required by the assignments and project as well as write technical documents.

Students are also expected to have an introductory knowledge of linear algebra and calculus. Completed material in computer graphics topics (CSC 433/533 or equivalent) is helpful but not required, nor is undergraduate data visualization (CSC 444 or equivalent) required. While students majoring in areas other than CSC are encouraged to enroll, certain topics may prove challenging. Please contact the instructor if you are unsure if you satisfy the prerequisites.

Scheduled Activities (Assignments and Deliverables)

Assignments (55% of total grade)

This class will have seven assignments, worth 55% of your total grade (six programming assignments and one “pre-assignment”). A00 is a warmup assignment to make sure you are comfortable with the tools we will use and the submission system. The remaining six assignments require you to demonstrate a visualization approach, implemented in d3. Each will have a duration of two weeks from their official posted date to when they are due. A00 is worth 1% while the remaining six assignments are worth 9% each.

Each of the six programming assignment will also include a written portion as well. Each written component accounts for 2.5% of your total grade, and thus together these written components will account for 15% of your total grade in this class. Written assignments are in lieu of a midterm or final exam, and will be used to gauge critical understanding of the reading associated with the span of time for the assignment as well as how the concepts mesh into practical implementations.

		Total Project Percentage:			35

Design Critiques (5% of total grade)

Besides assignments and the project, all students will perform one design critique for a visualization of their choice found from popular such as a newspaper, textbook, or magazine. Scientific magazines such as Nature or Science are allowed, but visualization journals and venues, where the topic of the work in question is primarily visualization, is not allowed.

Each week several students will post a design critique on our Piazza site. You are responsible to post one design critique during the semester and to actively participate in a discussion of a critique each week. Thus, the due dates for these are rolling.

Class Participation (5% of total grade)

This class participation grade is the instructor’s subjective judgement of the student’s contribution to a lively classroom atmosphere. He will consider mainly active, informed participation in classroom discussions, and homework reviews. Obviously, students not attending class are not contributing in this way.

While the instructor does not grade on attendance, nor is attendance required for the course, you are obligated to participate in class to receive credit for this portion of your grade. Participation will also take place as a component of design critiques – on the weeks that you are not posting a critique, you should take the opportunity to discuss it on Piazza.

Final Examination

There will be no final examination for this course, as you will conduct a summative final project.

Grading Policies

Grading Scale

Grades will be assigned based on the following scale:

A >= 90%
80% <= B < 90%
70% <= C < 80%
60% <= D < 70%
E < 60%

Grading will be based on performance on the set of assignments, project, design critiques, and class participation:

Programming Assignments: 55%
Project: 35%
Design Critiques: 5%
Class Participation: 5%

Each assignment description will include a specific rubric for how it is graded. Scores on such assignments will be weighted according to the relative point value of each assignment as highlighted above.

Department of Computer Science Grading Policy

Instructors will explicitly promise when every assignment and exam will be graded and returned to students. These promised dates will appear in the syllabus, associated with the corresponding due dates and exam dates.
Graded homework will be returned before the next homework is due.
Exams will be returned “promptly”, as defined by the instructor (and as promised in the syllabus).
Grading delays beyond promised return-by dates will be announced as soon as possible with an explanation for the delay.

Programming assignments and project milestones will be graded by one week after the due date and returned to students before the next homework is due. If exceptions have to be made occasionally, the instructor will inform the students about the delay and the reason for it.

Requests for incomplete (I) or withdrawal (W)

Request must be made in accordance with University policies, which are available at http://catalog.arizona.edu/policy/grades-and-grading-system#incomplete and http://catalog.arizona.edu/policy/grades-and-grading-system#Withdrawal, respectively.

Dispute of Grade Policy

After receiving any grade for any submission, a student has 24 hours to respond to the instructor with any disputes in an email with the subject “Grade Dispute”. Such a response must enumerate a specific set of disputed items for the submission and provide evidence that each item was improperly graded. The instructor will then completely regrade the entire submission, including both the disputed items as well as non-disputed items, with the potential for all aspects of the grade to change.

Submission, Lateness, and Revision Policy

All graded work has a fixed due date. Revisions and resubmissions after grading will not be accepted.

Submission for programming assignments will be due on 3:29:59PM of the due date unless otherwise noted. A late submission will receive a penalty of 10% per day for each work day it is late, up to a maximum of 5 days late. This penalty is applied multiplicatively: the instructor will first grade your assignment without penalty and then multiply your earned grade by \((1-0.1N)\) where \(N\) is the number of days late.

Grades for assignment submitted late may not be posted within the same time frame as assignments submitted on time, but the instructor will make their best effort to expedite the grading of late submissions.

Department and University Policies

Department of Computer Science Code of Conduct

The Department of Computer Science is committed to providing and maintaining a supportive educational environment for all. We strive to be welcoming and inclusive, respect privacy and confidentiality, behave respectfully and courteously, and practice intellectual honesty. Disruptive behaviors (such as physical or emotional harassment, dismissive attitudes, and abuse of department resources) will not be tolerated. The complete Code of Conduct is available on our department web site. We expect that you will adhere to this code, as well as the UA Student Code of Conduct, while you are a member of this class.

Classroom Behavior Policy

To foster a positive learning environment, students and instructors have a shared responsibility. We want a safe, welcoming, and inclusive environment where all of us feel comfortable with each other and where we can challenge ourselves to succeed. To that end, our focus is on the tasks at hand and not on extraneous activities (e.g., texting, chatting, reading a newspaper, making phone calls, web surfing, etc.).

Students are asked to refrain from disruptive conversations with people sitting around them during lecture.

Some learning styles are best served by using personal electronics, such as laptops and iPads. Nevertheless, these devices can be distracting to other learners. While all students are welcome to use personal electronics in class, they must be used in a way that does not disrupt either the instructor or other students’ experience.

Students observed engaging in disruptive activity will be asked to cease this behavior. Those who continue to disrupt the class will be asked to leave lecture or discussion and may be reported to the Dean of Students.

Threatening Behavior Policy

The UA Threatening Behavior by Students Policy prohibits threats of physical harm to any member of the University community, including to oneself. See http://policy.arizona.edu/education-and-student-affairs/threatening-behavior-students.
