Visualization is the graphical communication of data and information for the
purposes of presentation, confirmation, and exploration. For thousands of
years, images have been used to convey numbers, concepts, and relationships
using techniques such as maps, icons, graphs, and other visual forms. In the
past 2 decades, visualization has evolved into a discipline, drawing from such
fields as graphics, human-computer interaction, perceptual psychology, and
The goal of this course is to expose students to the field of data
visualization and familiarize them with the stages of the visualization
pipeline, including data modeling, mapping data attributes to graphical
attributes, existing visualization techniques, tools, and paradigms, perceptual
issues, and evaluating the effectiveness of visualizations for specific data,
task, and user types.
Interactive Data Visualization: Foundations, Techniques, and Applications, by
M. Ward, G. Grinstein, and D. Keim. ISBN 9781568814735.
Additional Resources: All documents for the course will be made available
at the website
http://www.cs.wpi.edu/~matt/courses/cs525D/. Also, I
extensive library of books and conference proceedings on visualization (see the
list below). If there is any topic that you'd like to delve deeper into, or
look for clarification or alternate viewpoints, feel free to borrow any of my
collection for a week or two.
Each week the assignment will consist of several components, each with an
expected amount of time you should dedicate:
- Reading: Each week we will focus on a different chapter of the book. I
would expect the reading to require 2-3 hours per week.
- Programming Project: Each student, either working alone or in pairs,
responsible for selecting data that is of interest to them and designing and
developing a visualization tool to display and explore that type of data.
You should be prepared to discuss in class your data set and the approaches to
visualization you are considering or developing (see schedule below).
For the end of the term you should create a report (5-10 pages) and a poster
about your project. I expect each student to spend 3-5 hours a week on their
- Research Project: Each student (individual) is responsible for
researching a topic
in visualization, reviewing 2 or more papers on the topic, and creating a
report and 10-15 minute talk on the topic. In the ideal situation, this topic
would be related to your programming project (either on the same kind of data
or using a technique that you are planning to implement). The talks will be
presented throughout the term (see schedule below). I expect this activity
to take between 5 and 10 hours of total effort.
- Tool Testing: Each student (individual) should identify an existing
tool for data
visualization and create a web page to describe the tool and show examples of
its use. When you are finished with the website, send me a copy in a zip file
and I'll add it to the course website. It is due by the end of the semester.
I expect this activity to take between 5 and 10 hours of total effort.
- Book Suggestions: My co-authors and I are working on the second edition
of the textbook for this course, and would like each of you to contribute to
it! Each week you should do one or more of the following (up to 2 hours of
work per week):
Additionally, if you spot any typos or grammar issues, please let me know.
- Identify a paper that the book has not referenced (especially recent ones)
that are appropriate for the topic of the chapter. If possible, indicate
where in the chapter it could be referenced and briefly why you think it is
- Write a new exercise or project for the end of the chapter.
- Write pseudo-code for an algorithm that would be appropriate for the
chapter (if applicable).
- Write code to implement an algorithm from the chapter, using either Java
or C++ (like those in the book appendix), or a language of your choice (e.g.,
Processing). Don't just reimplement one of the algorithms already programmed
in the book.
There will be no exams given for this course.
The steps of the programming
project are as follows:
- Select some socially relevant data set or information source as
a focus for visual analysis. Confirm your topic with Prof. Ward.
- locate 1 to 3 papers that present methods for visualizing
this kind of data. Summarize and include references to them in your project
- Design or extend a visualization to allow exploration of your
data/information. You are not allowed to just use Excel! There should be some
- Explore your dataset and identify a modest number of "interesting"
features in the data.
- Write a short (between 5 and 10 pages, single spaced) paper
describing the data, the papers you read related to visualizing this type of
data, the process you followed in developing your visualization, the methods
used for exploration, and the things you discovered. Include screen shots
and relevant references.
- Create a poster describing your data and how you visualized it. Show
more than one view and, if possible, more than one data set.
This project is due by the start of our last class. We will hold a poster
session for all to see what everyone has been doing.
Your grade will be roughly computed as follows:
- Programming Project: 60%
- Research Project: 15%
- Tool Testing: 15%
- Book Suggestions: 10%
For each part, I will assign a letter grade, and your final
grade will be a weighted average of these grades. The rough grading will be
check/B = met expectations, check+/A = exceeded expectations, check-/C =
did not meet expectations, X/F insufficient to earn passing grade. Late
assignments without prior permission may
have a negative impact on the grade.
I will grade the programming project based on all aspects of the work,
including the progress reports (presentations), report, and poster.
Copying the work of others and turning it in as your own is considered academic
dishonesty, and is strictly forbidden in this class. Violators of this policy
will receive a 0 grade for the assignment, and the incident will be reported to
the department chair and the Dean of Students' Office.
You can use whatever computer you have at your disposal, as long as
your programs can be demonstrated on a machine on
OpenGL, Java2D, Java3D, Processing, or X can be used for software
whatever language you used in your graphics course will do. In most cases,
you can get by with 2-dimensional graphics, though for some types of
visualization, 3-D is essential. When you turn in your assignments, please
include instructions for compiling and executing the program. I may decide
to instead have you demonstrate the programs in action if it is too
time-consuming for me to figure out how to build and run them.
It may also be possible to build your assignments using an existing
visualization tool as a base (you are expected to add code to these). Some
visualization tools that you can download and test include:
- XmdvTool -
- SpiralGlyphics -
- OpenDX -
- Prefuse -
- DeVise -
- VTK -
- CViz -
- VolVis -
- extra points for finding others (other than WPI-developed)

Every programming project group should decide on their datasets and have
them approved by me by week 3. Thus you should plan to e-mail me your
preliminary choice (and maybe a second choice) by February 1.
The programming project teams will be divided into Group A and B, and each
will present their progress 3 times during the term. I will assign teams to
groups once I have approved the dataset choices. For the research projects,
will be 4 sessions for people to do their 10-15 minute talks. I will seek
volunteers for week 4, and assign the rest at random.
