Sunburst Papers

Radial, Space-Filling Hierarchy Visualizations

Georgia Institute of Technology

Presenter: Marcus Beale

slide7

TreeMap(TM)

Vs.

Sunburst(SB)

slide9

Experimental Results

Experiment One

Experiment Two

For file search tasks, people who used SB first did better

In both phases. Along with some other results this suggest

That SB is easier to learn initially than TB.

slide10

Subjective Results

51 out of 60 people preferred SB overall.

slide11

Experimental Design Problems

  • 1. Too Many Variables. Attempted to answer too many
  • questions at once.
  • 2. Most Conclusion are NOT statistically significant.
  • Even if they were SS – would they apply?
    • Would the means be different enough to care?
    • Does this apply to all hierarchies?
    • c) What about all those failures we through out?

Suggestions

Make users perform only one type of task, but

over many hierarchies, with more samples.
