The three basic questions to ask when deconstructing a visualization are:

  1. What data is being shown?
  2. ???
  3. How has the visualization been designed?
  • Why is the data presented?

I have a dataset that I’d like to visualize that describes major world events over the last year. The dataset has an attribute for the month the event occurred in, the number of countries involved in the event (e.g., January, February), and the genre of event (e.g., political, social, environmental). How would you categorize the data types of these three attributes respectively?

  • Ordinal, Continuous, Categorical
  • Ordinal, Ordinal, Categorical

How might we best indicate that a set of datapoints are related?

  • Place them all in the spatial envelope.
  • Make them all salient.
  • Make them all the same hue.

I have a dataset that has Temperatures, Elevations, and Snowfall Depths for various mountain tops around the world. If my stakeholders care most about comparing temperatures, what visual channel should I use to communicate temperature?

I have a node-link diagram that has too much visual clutter to read effectively. Which of the following is not likely to reduce the amount of clutter in the graph?

  • Aggregate groups of connected nodes into single, larger nodes
  • Make the graph smaller
  • Organize the nodes such that groups of highly related nodes are close together

Why is uncertainty important in visualization?

  • It provides information about how likely our conclusions are to be correct
  • It limits the number of available visualization designs
  • It allows us to aggregate data

What is a key disadvantage of bar charts with error bars compared to violin plots?

  • Bar charts are more complex than violin plots
  • Bar charts can only represent small datasets
  • People think points below the mean are more likely in bar charts

True or False: Uncertainty visualization can only be used when the data is aggregated by category?

  • True
  • False
  • It depends on the type of visualization used.

Why might it be useful to not explicitly encode uncertainty?

  • Uncertainty visualizations make decision making harder
  • People can infer statistics about a dataset robust to outliers and other potential errors
  • People aren’t good at reasoning under uncertainty

    Soon after its appearance, strip poker showed up in a range of movies during the 30s and 40s, making this game a cult one. For instance, strip poker appeared in the controversial movie called The Road to Ruin (1934) – the film depicted a hard fate of a young schoolgirl whose life was ruined by sex and drugs. Being both spicy and provocative, the movie somehow earned almost $3 million. Maybe it was the strip poker’s credit? hannahjames710 Age 26 Ultimately, the idea of playing poker and betting on your clothes instead of chips or cash is as old as the game itself. Being born on the banks of the Mississippi River, in New Orleans, it is generally accepted that strip poker roots back to the 19th century. Considered to gain its popularity first in the “vulgar” and ill-mannered places of that time, like houses with red doors (if you know what we mean), strip poker soon had gone much far beyond the cathouses.
