CS 397Z / CS 632D - Visual Computing

Midterm Take-home Exam

Dr. Francis T. Marchese

 

Due Date: Tuesday, November 2, 2010 at 5:00PM.

 

In 2007 Ralph Lengler & Martin J. Eppler published a paper entitled “Towards A Periodic Table of Visualization Methods for Management,” (Lengler and Eppler, 2007) that was later transformed into a webpage.

 

The problem with this table is that the periodic table of the elements is a poor metaphor for representing anything but the chemical elements. Since its appearance, this table has been much criticized (e.g. see Few).

 

The idea of organizing the basic concepts and methods of visualization into a easily accessible form is a good one. Thus, for your midterm exam, you are to redesign all or part of this table so it makes more sense.

 

To begin, read Wainer’s (1992, 1997) rules for evaluating table quality. And see Marchese (2008) for how they are used to evaluate the periodic tables of the elements. Then take a section of this table, say for example data visualization, and try to work out a better tabular structure. Look at the number of dimensions, types of charts, etc. to see what kinds of relationships exist. Try to find patterns. Then come up with a table design that reflects those patterns.

 

The process you follow is up to you. You may discuss the exam with anyone. But, if an individual has provided an idea that you have used for your design, give that person credit. If you use any kinds of other resources for you design – reference them. Here, the process is as important as the product.

 

You should turn in an electronic document that contains your table design. You can sketch it out, use any visualization or drawing tool. You should discuss the process that went into the design, including any other designs you considered along the way. You should defend your design by using Wainer’s rules.
