  11. TYPES OF DATA

  12. VISUAL VARIABLES Position Changes in the x, y location Size Change in length, area, or repetition Color Hue Changes in hue at a given value Shape Color Value Changes from light to dark Orientation Changes in alignment Texture

SIMPLICITY Humans have a limited capacity for processing input 19348405984950684900256986417536922268921478562597862525879635678895215678555642189751247002545697015978602368259746210102549856789516528916 19348405384950684900256986417536922268931478562593862525379635678895215678555632189751247002545697013978602368259746210102543856783516528916 VS

  21. PROXIMITY Objects that are closer to each other are perceived as being more related than the ones that are not positioned near them

  24. SIMILARITY If two objects have similar characteristics, we perceive these objects to be more related than the ones that don’t share these qualities.

  25. SIMILARITY slide 2 SIMILARITY If two objects have similar characteristics, we perceive these objects to be more related than the ones that don’t share these qualities.

  26. GESTALT PRINCIPLES APPLIED Gestalt Principles • Proximity • Similarity • Simplicity (an attempt, at least) Visual Variables • Hue • Position Image from Economist.com

  27. CHOOSING A VISUALIZATION CHOOSING A VISUALIZATION

  28. PRACTICAL DESIGN TIPS • Be mindful of cultural and symbolic connotations of color • Get it right in black and white – accessibility for people who are color blind • Stick to ~6 or fewer different colors • Follow familiar patterns and structure Image from d3js.org

  29. DESIGN CRITIQUE Image from Fundamentals of Data Visualization by Claus O. Wilke

  30. DESIGN CRITIQUE Continued DESIGN CRITIQUE The colors are misleading! • Shifts between hues look abrupt • Unintentionally draws attention to blue areas • 0% and 100% would look more similar than 0% and 50% • Defies conventional color associations Image from Fundamentals of Data Visualization by Claus O. Wilke

  31. DESIGN CRITIQUE Slide 3 DESIGN CRITIQUE The colors are misleading! • Shifts between hues look abrupt • Unintentionally draws attention to blue areas • 0% and 100% would look more similar than 0% and 50% • Defies conventional color associations Solutions: • Monochromatic palette • Colorbrewer2.org Image from Fundamentals of Data Visualization by Claus O. Wilke

  34. DESIGN CRITIQUE Slide 6 DESIGN CRITIQUE The colors are meaningless! Solution: • Choose 1, less saturated color for all the bars Image from Fundamentals of Data Visualization by Claus O. Wilke

  36. DESIGN CRITIQUE Slide 8 DESIGN CRITIQUE Too many colors! Image from Fundamentals of Data Visualization by Claus O. Wilke

  37. DESIGN CRITIQUE Slide 9 DESIGN CRITIQUE Too many colors! Solutions: • Color code dots by region of the US, rather than individual state • Selectively label dots on the chart to draw attention to outliers or interesting cases Image from Fundamentals of Data Visualization by Claus O. Wilke

  38. ASSIGNMENT ASSIGNMENT Data visualization Hall of Fame/Hall of Shame Find an example of a data visualization that you think is either especially effective or especially ineffective. Post on the discussion board with a link to the visualization and the answers to the following questions: • What is the data relationship that is being represented? • How is the creator representing it? • Why do you think this visualization is especially effective/ineffective? Image from the Junkcharts blog

  39. ADDITIONAL RESOURCES • Document on Moodle • List of visualization blogs and galleries for your assignment • Color choosing tools and accessibility information • Two supplemental resources • The best stats you’ve ever seen, by Hans Rosling, founder of Gapminder • 39 Studies of Human Perception in 30 minutesby Kennedy Elliot, graphics editor at the Washington Post

  43. Assignment ASSIGNMENT Finding Data Find and download a dataset (or datasets) that you think would make for an interesting visualization. On the discussion board, attach the file as a CSV or Excel worksheet and answer the following questions: • What information is contained in this dataset? • What would be your goal in visualizing the data? • Would you need to further curate the data to achieve your goal? (ie delete unnecessary information or extract only certain information) Photo by Simson Petrol on Unsplash.com
