Tidy Tuesday

Iterative Viz

At your table,

check in with each other (e.g. how was the weekend, what you looking forward to, what you are struggling with)

Let’s review from the beginning of semester.

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

Let’s consider Fig 3.8, 3.9, 3.11. What is effective? What could be improved?

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?

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.

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.

You’ll present Weds and Friday to different groups of people.

Consult with your project group and work on creating a visualization.
