Effective Visuals

• Be ethical and honest

• Consider glyph choice

  • easy or hard to perceive?

• Consider color choices

  • color blind friendly? cultural associations?

• Facilitate comparison

  • e.g. position through order on axis or faceting, calculate and present the difference or ratio

• Use contrasts to draw attention

  • e.g. yellow, red, orange draw attention in nature of green, brown, blue

Presenting a Visual

When preparing to present a visualization, consider:

• What context does the audience need to understand the visual? (W’s?)
• Does the visual have enough text annotation and guides to be understood with minimal explanation?
• What aspects of the visual should you explain to provide necessary orientation?
  • Walk through guides (axes, color legend, etc.)
• What aspects of the visual do you want to draw attention to?
  • What comparison are you wanting to highlight?

Preparing for this Week

• Create 1 effective visualization from your project data that tells a story
  • Each person in a project group should make their own unique visualization
• Prepare a 2 minute oral presentation (orientation and explanation) of your visualization.
  • Consider the questions on the last slide.

Tuesday, April 18th in class

In small groups of 4 people,

• you’ll present your visualization (2 minutes)
• discuss as a group ways of improving the visualization to make it more effective (8 minutes)

Each of the 4 individuals will take a turn to present.
