Teaching Data VisualizationResources
Questions for Discussion
Why is data visualization important in your field?
What tools do you use to generate images?
What do your data visualization assignments look like right now?
What tools are available to your students?
How can your department or small groups of faculty encourage core learning in this area? What are you doing already?
Be sure to give students learning materials related to data visualization and information design. Show examples of good and bad design.
Scaffold assignments so that students create graphics for more and more complex data as the semester goes along.
Allow students one exercise or assignment to explore the myriad concepts of data visualization before they apply it to data from your course.
Establish Data Vizualiation workshops so that students understand the importance of audience and interpretation.
Invite a guest lecturer to cover what you can’t!

Tufte’s Fundamental Principles of Analytical Design
1: Show comparisons, contrasts, differences.
2: Show causality, mechanism, explanation, systematic structure.
3. Show multivariate data; that is, show more than 1 or 2 variables.
4. Completely integrate words, numbers, images, diagrams.
5. Thoroughly describe the evidence. Provide a detailed title, indicate the authors and sponsors, document the data sources, show complete measurement scales, point out relevant issues
Tufte’s Advice for Graphical Displays
- show the data
- induce the viewer to think about the substance rather than about methodology, graphic design, the technology of graphic production, or something else
- avoid distorting what the data have to say
- present many numbers in a small space
- make large data sets coherent
- encourage the eye to compare different pieces of data
- reveal the data at several levels of detail, from a broad overview to the fine structure
- serve a reasonably clear purpose: description, exploration, tabulation, or decoration
- be closely integrated with the statistical and verbal descriptions of a data set.
