  1. Information design Instructor: Heiko Spallek, DMD, PhD Text: Tufte ER, The Visual Display of Quantitative Information, Graphics Press (1983). January 23rd, 2003 Dental Information Systems #2201

  2. Agenda What is information design? What is an information designer? Graphics principles Graphical excellence Information design by the National Geographic Lie factor Data density Criticize a manual Design a graphic with pencil and paper Example: Computer Usage among Dentists (What is good? What is bad?)

  3. Information Design is … ... the communication of complex information through clear language and design. Information Design Unit: http://www.idu.co.uk/ ... a theoretical structure by which information is organized and presented. The separation of document design into information and graphic design ... Mike Fletcher, University of Waterloo ... applying the principles of design to the selection, organization, and presentation of information. From paragraphs to pie charts and CD-ROMs to Websites, it is a means of building effective information products. Ken Dow, Maricopa Information Design ... based on a process view of intentional transformation of data-elements into information ... in order to obtain an understandable representation. Peter Bogaards, TS Design, Amsterdam, now of Razorfish

  4. An information designer is ... … the individual who organizes the patterns inherent in data, making the complex clear … a person who creates the structure or map of information which allows others to find their personal path to knowledge … the emerging 21st century professional occupation addressing the needs of the age focused upon clarity, human understanding, and the science of the organization of information Richard Saul Wurman Information Architects

  5. Graphics instruments for reasoning about quantitative information graphical integrity graphical competence demands 3 skills: substantive, statistical, artistic Design is choice.

  6. Principles I small, noncomparative, highly labeled data sets  tables time-series: descriptive chronology is not causal explanation visual representation of the data consistent with numerical representation show data variations, not design variations The only way to think clearly about money over time is to make comparisons using inflation-adjusted units of money. The number of information-carrying (variable) dimensions depicted should not exceed the number of dimensions in the data.

  7. Principles II clear, detailed, thorough labeling  defeat graphical distortion and ambiguity Above all else show the data (data ink). Forgo chartjunk (vibrations, grids, ducks) Range frame should replace non-data-bearing frame. The same ink should often serve more than one graphical purpose. Because they do have a natural visual hierarchy, varying shades of gray show varying quantities better than color. Organize and order the flow of graphical information presented to the eye.

  9. Graphical Excellence is well-designed presentation of interesting data. consist of complex ideas communicated with clarity, precision, efficiency. gives to the viewer the greatest number of ideas in the shortest time with the least ink in the smallest space. is nearly always multivariate. requires telling the truth about the data. Graphical elegance is often found in simplicity of design and complexity of data.

  10. Info chart #1 Good information design by NG? Connecting the planet--the Fuller Projection Map What is good about this map? What is bad about this map?

  11. Info chart #2 Information design in outer space Salyut 6: Cyclogram by Grechko & Romanenko (1977/1978)

  12. Lie Factor Size of effect shown in graphic Lie Factor = ----------------------------------------- Size of effect in data Edward Tufte The Visual Display of Quantitative Information page 57

  13. Edward Tufte The Visual Display of Quantitative Information page 43 Data density number of entries in a data matrix data density of a graphic = ----------------------------------------- area of data graphic

  14. In-class assignment #1 Criticize a manual Ortlieb Handlebar Bag “Ultimate 2” (February 2000) What is good about this manual? What would you improve? Which design problems do you recognize?

  15. In-class assignment #2 Design a graphic Follow the principles learned. Explain the reasoning for your design choices. What should be improved?
