CSC 444 - Data Visualization (Fall 2021)

T/R 9:30-10:45am, Spch & Hearing Sci, Rm 205

Course Syllabus


Description of Course

This course will present the fundamentals of data visualization, the art and science of using a computer to generate visual depictions of data. The course will present the foundations of graphic design, perceptual psychology and cognitive science, as well as the algorithmic basis for many for the visualization techniques. While statistical techniques may determine correlations among the data, visualization helps us frame what questions to ask.

The course is targeted at students looking for effective ways of understanding data from their own fields, as well as students interested in learning the fundamentals that will enable them to build and improve the state of the art. The successful student will learn to design, critique and improve data visualizations.

Course Prerequisites or Co-requisites

CSC 335 (Object-Oriented Programming and Design) and CSC 345 (Analysis of Discrete Structures) 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.

We will write most of our code using the web stack. This means we are targeting modern web browsers, and writing our programs in a combination of HTML, CSS, and JavaScript. If you don’t know these technologies, you will be expected to learn them. CSC 337 (Web Programming) is not a formal pre-requisite for this course, but it might be considered helpful.

Course Objectives

The content of the course is split roughly in three distinct aspects of visualization: mechanics, principles, and techniques.

Mechanics: You will learn how the modern web stack enables performant and portable data visualization programs. You will learn to use some of the most popular data visualization libraries, you will learn how they are implemented, and their limitations.

Principles: These principles are based on perceptual psychology and physiology, and how they constraint the algorithms for displaying data effectively and efficiently. They also intertwine with a collection of design principles the design process that includes abstracting, encoding, and interacting with data.

Techniques: You will learn the fundamental algorithms behind many of the techniques created to display data effectively.

Class Participation (10% of final 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 be gauged through virtual mechanisms, such as contributions to the class discussions on Piazza.

Midterm Examination (12% of final grade)

A midterm exam will be held in class on Tue., Oct 12, 9:30-10:45am, and it will cover all material discussed in class prior to the date of the examination.

Final Examination (18% of final grade)

The final examination will be comprehensive. A review will be conducted on the final lecture.

Exam Date/Time/Location: Sun., Dec 12 8:00am - Tues., Dec 14, 10:00am, Spch & Hearing Sci, Rm 205

Submission, Lateness, and Revision Policy

All assignments have a fixed due date. Revisions and resubmissions after grading will not be accepted.

Submission for programming assignments will be due on 9:29:59AM 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.

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 at a deadline set in consultation with the instructor.

Course Communications

We will use official UA email and Piazza as the primary mode of contact. D2L will be used only for the instructor to securely distribute the course calendar, class materials, and grades to students.

Grading Scale and Grading Policies

Grades will be assigned based on the following scale:

Grading will be based on performance on the set of assignments, the midterm and final exam, and class participation:

Each assignment description will include a specific rubric for how it is graded, typically out of a score between 0 and 100. 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.).

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.

Accessibility and Accommodations

At the University of Arizona, we strive to make learning experiences as accessible as possible. If you anticipate or experience barriers based on disability or pregnancy, please contact the Disability Resource Center (520-621-3268, https://drc.arizona.edu/) to establish reasonable accommodations.

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 https://deanofstudents.arizona.edu/policies/code-academic-integrity.

Uploading material from this course to a website other than D2L (or the class piazza) is strictly prohibited and will be considered a violation of the course policy and a violation of the code of academic integrity. Obtaining material associated with this course (or previous offerings of this course) on a site other than D2L (or the class piazza), such as Chegg, Course Hero, etc. or accessing these sites during a quiz or exam is a violation of the code of academic integrity. Any student determined to have uploaded or accessed material in an unauthorized manner will be reported to the Dean of Students for a Code of Academic Integrity violation, with a recommended sanction of a failing grade in the course.

The University Libraries have some excellent tips for avoiding plagiarism, available at http://new.library.arizona.edu/research/citing/plagiarism.

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 of Arizona is committed to creating and maintaining an environment free of discrimination. In support of this commitment, the University prohibits discrimination, including harassment and retaliation, based on a protected classification, including race, color, religion, sex, national origin, age, disability, veteran status, sexual orientation, gender identity, or genetic information. For more information, including how to report a concern, please 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.
