Linear Diagram Design Study Part A

The work described here is part of a larger study on the design of linear diagrams.

Design Study Part A. Should we minimize the number of line segments?

Here the questions are presented in the random order, as they would appear to the participants. The pages below echo the results, in the study, these answers were sent to Mechanical Turk in a url query string.

• Line Segment Minimization
• Random Column Order

The visualizations were generated from source data derived from SNAP Twitter ego networks. The files listed here are from this .gz file: http://snap.stanford.edu/data/twitter.tar.gz.

Anonymised study results in csv format. The time column records the time spent on the question page in seconds. The fraction correct column gives the proportion of buttons in their correct state (selected or not selected). The data here is from the participants who answered both attention testing questions correctly.
