Chapter.03 Presentation Transcript

  • 1. Determining Effective Data Display with Charts
    Chapter 3
    “Information is a source of learning. But unless it is organized, processed, and available to the right people in a format for decision making, it is a burden, not a benefit.”- William Pollard
  • 2. Chapter Introduction

  • 5. Visualizing Data
  • 6. Data Graphics Principles (Tufte)
    Above all else, show the data
    Maximize the data-ink ratio, within reason
    Erase non-data-ink, within reason
    Erase redundant data-ink, within reason
    Revise and edit
  • 7. Data Graphics Principles
  • 8. Data Graphics Principles
    “Above all else show the data”
    Reminder not to clutter a chart by adding unneeded illustration or decoration.
    “Maximize the data-ink ratio”
    Refers to the portion of ink that is devoted to displaying the data vs. the portion of graphic that can be removed without losing the data.
  • 9. Data Graphics Principles
    “Erase non-data-ink”
    Non-data-ink is a part of the chart that decorates more than informs.
    “Erase redundant data ink”
    Redundant data ink is ink that repeats information.
    “Revise and edit”
    Revise and edit charts like you would a piece of writing.
  • 10. Data Graphics Principles
