  1. 1. Data Driven Societies: From Data/Tech to DataViz Professors Gaze & Gieseking
  2. 2. Data & Technology & Statistics, Oh My History of data and technology + Data visualization Statistical thinking

  5. 5. Tufte: Snow’s Cholera Map 1854
  6. 6. Tufte: Challenger O’Rings 1987
  7. 7. Tufte: What is Bad DataViz? ✦ Disappearing legend ✦ Chartjunk - visual elements in charts and graphs not necessary for their comprehension ✦ “Chartjunk indicates statistical stupidity, just as weak writing reflects weak thought. ... Good design brings absolute attention to data.” (48) ✦ Lack of clarity in depicting cause and effect ✦ Wrong order
  8. 8. Yau: Visualization as Medium flowingdata.com/2010/10/18/true-size-of-africa/

  10. 10. Tufte & Yau: What is Good DataViz? Tufte Yau Certain key rules must be applied: You may need to throw out the rules but these ideas generally apply: ✦ ✦ ✦ ✦ Place data in appropriate context to assess cause/ effect Make quantitative comparisons Consider alternative explanations and contrary cases Assess possible errors in data ✦ Let the type of visual and tool fit question ✦ Visualization is storytelling ✦ Entertainment and humor can be helpful ✦ Let data guide design ✦ Recognize how interface interactions with data
