CSC 544 - Data Visualization

Course Syllabus



Course Description

This course introduces material on the theory and practice of designing effective visualizations of data from numerous sources. A broad overview to the field is presented, covering principles, methods, and techniques that are foundational to both information and scientific visualization.

Data visualization is a field of growing importance that combines background expertise in computer graphics, scientific computing, data mining, and image processing. It couples these fields with artistic, psychological, perceptual, and interactivity concerns. The techniques learned in this class are broadly applicable to all fields in engineering and science, where the explosion of data we are now able to generate demands effective presentation and analysis.

Course Prerequisites or Co-requisites

Students are expected to have advanced programming skills in C++ and introductory knowledge of linear algebra and calculus. Completed material in computer graphics topics (e.g. CSC 433/533 or equivalent) is helpful but not required, nor is undergraduate data visualization (i.e. CSC 444). 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.

Course Policies

Absence and Class Participation Policy

The UA’s policy concerning Class Attendance, Participation, and Administrative Drops is available at http://catalog.arizona.edu/policy/class-attendance-participation-and-administrative-drop

The UA policy regarding absences for any sincerely held religious belief, observance or practice will be accommodated where reasonable: http://policy.arizona.edu/human-resources/religious-accommodation-policy.

Absences preapproved by the UA Dean of Students (or dean’s designee) will be honored. See https://deanofstudents.arizona.edu/absences.

Participating in the course and attending lectures and other course events are vital to the learning process. That said, attendance is not required for lectures. Students who miss class due to illness or emergency are not required to bring documentation from their health-care provider or other relevant, professional third parties. Nevertheless, class participation is an important part of your grade in this course, and it is impossible for a student to participate and the instructor to gauge participation if a student does not attend.

Late Instructor

Your instructor will make every effort to be in class on time, or to inform you of any delay or cancellation. In the unusual event that he should not arrive in class or send word by 15 minutes from the class start time, the class is officially cancelled.

Makeup Policy for Students Who Register Late

Students who register after the first class meeting may make up missed assignments/quizzes at a deadline set in consultation with the instructor.

Course Communications

We will use official UA email as the primary mode of contact. In addition, Piazza will also be used. D2L will be used only for the instructor to securely distribute grades to students.

Required Texts and Readings

Additional Reference Reading Materials

Assignments and Examinations: Schedule/Due Dates

Programming Assignments

This course will involved 8 programming assignments, each spanning approximately two weeks from posting date to due date (except for the first assignment, which is much shorter). All programming assignments will be completed in C++, built with CMake and rely on the openFrameworks library. Certain assignments will also employ VTK.

Most assignments also will require a written assignment report that answers specific questions regarding design decisions and implementation details.

Design Critiques

In addition, 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.

Paper Quizzes

Staying up to date with current visualization research is an essential part of this course. Most lectures will involve at least one required reading material, frequently in the form of a related research paper. In addition, many lectures will include recommended reading, that is not required, but rather supplementary to the current lecture.

In lieu of a midterm, the instructor will solicit written responses, submitted electronically, that form ten quizzes on certain assigned readings. To prevent only selective readings, such quizzes will be assigned periodically and with no more than one weeks notice beforehand. All quizzes will be announced through Piazza.

Submission, Lateness, and Revision Policy

All programming assignments, design critiques, and quizzes have a fixed due date. Revisions and resubmissions after grading will not be accepted.

Submission for programming assignments, quizzes, and design critiques will be due on 11:59:59PM 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. 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.

Class Participation

The 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, quiz and homework reviews. Obviously, students not attending class are not contributing in this way.

One component of the participation grade will be evaluating the design critiques of others. Each week, design critiques will be analyzed by the class as a whole. Positive feedback and constructive criticism will be provided to the student(s) who completed that week’s critique.

Final Examination or Project

The final examination will be comprehensive. Quizzes will provide sample questions and a review will be conducted on the final lecture.

Exam Date/Time/Location: Tues, May 09, 8-10am, 701 Gould-Simpson

Grading Scale and Policies

Grades will be assigned based on the following scale:

Grading will be based on performance on the set of programming assignments, the class final exam, quizzes based on paper readings, design critiques, and class participation, using the following percentage distribution:

Each assignment will include a specific rubric for how it is graded, typically out of a score between 0 and 10. 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:

  1. 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.
  2. Graded homework will be returned before the next homework is due.
  3. Exams will be returned “promptly”, as defined by the instructor (and as promised in the syllabus).
  4. Grading delays beyond promised return-by dates will be announced as soon as possible with an explanation for the delay.

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.



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.).

Inclusive Excellence is a fundamental part of the University of Arizona’s strategic plan and culture. As part of this initiative, the institution embraces and practices diversity and inclusiveness. These values are expected, respected and welcomed in this course.

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.

Content Warning

While the instructor does not intend to include topics and/or course material includes content that are explicit or offensive in any way. The instructor will make every effort to provide advance notice when such materials may potentially be or potentially violate this intent. Please contact the instructor to discuss any content-related concerns, as alternative materials may be available.

Elective Name and Pronoun Usage

This course supports elective gender pronoun use and self-identification; rosters indicating such choices will be updated throughout the semester, upon student request. As the course includes group work and in-class discussion, it is vitally important for us to create an educational environment of inclusion and mutual respect.

Accessibility and Accommodations

Our goal in this classroom is that learning experiences be as accessible as possible. If you anticipate or experience physical or academic barriers based on disability, please let me know immediately so that we can discuss options. You are also welcome to contact the Disability Resource Center (520-621-3268) to establish reasonable accommodations. For additional information on the Disability Resource Center and reasonable accommodations, please visit http://drc.arizona.edu.

If you have reasonable accommodations, please plan to meet with me by appointment or during office hours to discuss accommodations and how my course requirements and activities may impact your ability to fully participate.

Please be aware that the accessible table and chairs in this room should remain available for students who find that standard classroom seating is not usable.

Code of Academic Integrity

Students are encouraged to share intellectual views and discuss freely the principles and applications of course materials. However, graded work/exercises must be the product of independent effort unless otherwise instructed. Students are expected to adhere to the UA Code of Academic Integrity as described in the UA General Catalog. See http://deanofstudents.arizona.edu/academic-integrity/students/academic-integrity.

The University Libraries have some excellent tips for avoiding plagiarism, available at http://www.library.arizona.edu/help/tutorials/plagiarism/index.html. Publicly available sources for code or other material, in small amounts, may be freely used if appropriately attributed. A good rule of thumb: when in doubt about whether the use of small snippets of code not your own in a programming assignment is allowed, first ask the instructor.

Selling class notes and/or other course materials to other students or to a third party for resale is not permitted without the instructor’s express written consent. Violations to this and other course rules are subject to the Code of Academic Integrity and may result in course sanctions. Additionally, students who use D2L or UA e-mail to sell or buy these copyrighted materials are subject to Code of Conduct Violations for misuse of student e-mail addresses. This conduct may also constitute copyright infringement.

UA Nondiscrimination and Anti-harassment Policy

The University is committed to creating and maintaining an environment free of discrimination; see http://policy.arizona.edu/human-resources/nondiscrimination-and-anti-harassment-policy

Our classroom is a place where everyone is encouraged to express well-formed opinions and their reasons for those opinions. We also want to create a tolerant and open environment where such opinions can be expressed without resorting to bullying or discrimination of others.
