Visual media are increasingly generated, manipulated, and transmitted by computers. When well designed, such displays capitalize on human facilities for processing visual information and thereby improve comprehension, memory, inference, and decision making. Moreover, visual representations may help to engage diverse audiences in the process of analytic, data-driven thinking.
In this course we will study techniques and algorithms for creating effective visualizations based on principles from graphic design, visual art, 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 participating in class discussions, students will have to complete several short data analysis and visualization design assignments as well as a final project.
There are no official prerequisites for the class, but the class is aimed at graduate students and advanced undergraduates. Familiarity with the material in CS147, CS148 and CS142 can be useful. Most important is a basic working knowledge of, or willingness to learn, web-programming, especially JavaScript, Vega-Lite and D3. Experience with data analysis applications (e.g. R, Python, Excel) is also helpful. While we will cover a little bit of JavaScript/Vega-Lite/D3 in class, most of the other APIs, applications and languages will not be taught in the course. However many introductory tutorials at the level required for the class are available on the web and we will help you find the relevant information as you need it.

Learning Goals
The goals of this course are to provide students with the foundations necessary for understanding and extending the current state of the art in visualization. By the end of the course, students will have:
- An understanding of key visualization techniques and theory, including data models, graphical perception and methods for visual encoding and interaction.
- Exposure to a number of common data domains and corresponding analysis tasks, including exploratory data analysis and network analysis.
- Practical experience building and evaluating visualization systems.
- The ability to read and discuss research papers from the visualization literature.
