This course enables you to transform data into persuasive and evidence-based visualizations. Visualizations are persuasive if they motivate actions in an intended audience. Visualizations are evidence-based if they are reproducible, functional, and truthful.
This course introduces and discusses the fundamental design principles and visualization technology that allows you to design, implement, and critique persuasive and evidence-based visualizations. In a data-rich environment, where decision-makers often drown in data but thirst for insight 1, mastering this course equips you with a moderate level of data literacy.
Data literacy is the ability to interpret, construct, and convey arguments through the functional and truthful visual presentation of data. Data literacy is a vital skill in our data-driven world. The chances are high that you will be interpreting and designing data visualizations throughout your career. The level of data literacy offered through this course allows you to establish a competitive advantage in Silicon Valley and the global marketplace.
You will learn to design and implement visualizations and critique the persuasiveness and evidence of visualizations. Upon successful completion of this course you will:
There is no required textbook for this class. Data visualization is a fluid topic that is covered in arts, design, and technology. You will find a lot of “conventional wisdom” out there (including in the books below). Please consume information with a critical mind.
I consider the following books as my ‘common core’ of contemporary data visualization:
The philosophy of data visualization:
The concepts of data visualization:
The technology of data visualization:
The practice of data visualization:
The hands-on elements in this course use Tableau Desktop, Jupyter/Python, R, and D3.js. I believe that experiencing data visualization through a variety of technology helps you to identify commonalities and important differences.
In the class meetings and assignments, we will work with all of these technologies. You are also free to use other technologies. Please discuss such plans with me before using different technologies.
PLEASE NOTE: I expect you to have Tableau Desktop installed on your laptop and R and Jupyter/Python ready to go.
It is my goal to spend the classroom time on conceptual and hands-on issues of data visualization. Therefore, we will only spend a minimal amount of time explaining how to use Tableau, Python, and JavaScript. I will introduce and explain all the code we need for the class meetings. If you want to use technology in your assignments but do not know it yet, the following resources will help you to get up to speed.
Tableau:
Python, Jupyter, R, and D3.js:
I am committed to your learning success. Please feel free to contact me with any questions regarding this course. If I am not able to help you myself, I will forward your request to someone who can.
Class meetings are Mondays and Wednesdays, 7:35 PM to 8:50 PM in Lucas Hall 307.
This course is centered around a reflective and practical approach to data visualization. Mondays are devoted to discussing design principles in data visualization. Wednesdays are lab sessions. During the lab session, you have the opportunity to work on a data visualization case study that allows you to practice the application of the design principle and technology. At the end of each lab session, you may be asked to present your results.
The following table shows the tentative schedule for the quarter and the assignments per week. Numbers in parentheses denote the maximum number of points you can achieve for the assignments). Submissions are always due on Sunday at 11:59 PM in the Pacific Time Zone.

The class reader is the virtual extension of the classroom. You use the class reader to collaboratively develop a deeper understanding of the conceptual and technical fundamentals of data visualization.
Your objective is to contribute in a meaningful way to the class reader every week. A meaningful contribution is defined as the following set of activities:
When contributing to the class reader, make sure that you understand the requirements of academic integrity as outlined below.
The structure of the class reader is as follows:
In the spirit of great examples of collaborative writing, we use GitHub to organize the writing process. You will use branches, projects, issues, pull requests, and wikis to manage your work efficiently.
Please note that this is a project that has been started in previous quarters.
I will evaluate your contribution to the class reader on a weekly basis (Week 1 to 10) using the following criteria.

The objective of the team project is to collaboratively develop a data product that is repeatable, inspectable, reusable, and diffable (i.e., you can see changes over time). A data product makes a complex data-driven argument using several data visualizations. You will work teams of up to five students.
The topic for the individual project is Gun Violence in the United States. We use the following data product as the inspiration: https://www.vox.com/policy-and-politics/2017/10/2/16399418/us-gun-violence-statistics-maps-charts. Please note that this just serves as an inspiration and starting point. You are expected to go beyond this example.
The challenge of a team project is to organize your team, hold one another accountable, and complement your skills and interests. At the end of the team project, your teammates will evaluate your contributions to the project. This evaluation may influence your grade for the team project.
The following table provides an overview of the deliverables for the team project.

I firmly believe that the mastery of data visualization requires constant practice. You will ace this course if you:
The Academic Integrity pledge is an expression of the University’s commitment to fostering an understanding of and commitment to a culture of integrity at Santa Clara University. The Academic Integrity pledge, which applies to all students, states:
“I am committed to being a person of integrity. I pledge, as a member of the Santa Clara University community, to abide by and uphold the standards of academic integrity contained in the Student Conduct Code.”
You are expected to uphold the principles of this pledge for all work in this class. For more information about Santa Clara University’s academic integrity pledge and resources about ensuring academic integrity in your work, see www.scu.edu/academic-integrity.
In particular, I expect that you give credit to any material (including but not limited to journal articles, web article, blog posts, images, data sets, and any media) that you have used for completing any assignment in this class. Being able to give credit by referencing sources consistently and correctly is evidence of mastery of a topic. It shows that you can construct original arguments that are backed with verifiable evidence. Failing to give credit is a sign of inadequate learning progress. It shows that you have not understood the topic well enough to formulate your own arguments in relation to already existing ideas.
During your work in this class, you will use, modify, or extend digital content that you have found online. You will also use libraries, APIs, code snippets, and data sets that have been created by others. In every piece of work (presentations, assignments, etc.), you must acknowledge work, source code, data sets, and any other content that was not produced by you. Acknowledgments must be easily identifiable, inseparable from your content, and must not violate licenses.
Failure to provide appropriate acknowledgments will result in an F grade for that assignment. Repeated failure to provide appropriate acknowledgments will result in an F grade for the entire course.
During the first class, we will discuss this digital content policy. After this class, I will strictly enforce this policy. If you have doubts, contact me.
I will support you in your learning in this class and beyond to the best of my abilities. If I am not able to help you myself, I will identify someone who can. I will evaluate your contribution solely based on the standards set by this syllabus. Changes to the syllabus will be highlighted, discussed during class sessions, and will be published on Camino.
By enrolling in this class, you agree to the requirements stated in this syllabus. You will operate with integrity in your dealings with me and your fellow students. You will engage the learning materials with appropriate attention and dedication and maintain their engagement when challenged by difficult learning activities. You will contribute to the learning of others and you will perform to standards set by this syllabus.
Mutual respect is the foundation of this course. No one will be criticized for being wrong. Appropriate conduct includes honesty, self-respect, respect for others, and compliance with university policies and standards. Computers in the classroom should be used only for completing course-related work and for taking notes; cell phones must be turned off or muted.
Please let me know via email during the first two weeks of the course if you have any conflicts between a course element (class meeting, assignment) and another vital commitment (another course, work, university-related extracurricular activities, religious commitments). At my discretion, I will you provide with alternative means to complete the course element.
I am aware that many of you have multiple commitments. You should attend at least 80 percent of all scheduled class meetings. If you miss more than 20 percent of scheduled classes, you will receive a reduction by one letter grade.
If you have a disability for which accommodations may be required in this class, please contact Disabilities Resources (Benson Hall 216, 408-554-4109) as soon as possible to discuss your needs and register for accommodations with the University. If you have medical needs related to pregnancy, you may also be eligible for accommodations. If you have already arranged accommodations through Disabilities Resources, please discuss them with me during my office hours as soon as possible.
While I am happy to assist you, I am unable to provide accommodations until I have received verification from Disabilities Resources. If you are in doubt of whether you are eligible for accommodations, I encourage you to contact Disabilities Resources (Benson Hall 216, 408-554-4109). The Disabilities Resources office would be grateful for an advance notice of at least two weeks.
