A Tale of Two Communities: Assessing Homophily in Node-Link Diagrams
This page serves as auxiliary material to our paper, entitled "A Tale of Two Communities: Assessing Homophily in Node-Link Diagrams". Its main purpose is to make available the stimuli and collected data for the presented user study.
NB: the degree of homophily (and bias) in these files are inverted. That is, a homophily value or bias assessment of X% in the paper is given here as (100-X)%.
Stimuli
The stimuli of our user study can be found on the two pages listed below. One page lists all the figures for the Path task, i.e., with highlighted nodes; the other lists the figures for the Bias task, i.e., without highlighted nodes.
Data
The data we collected may be downloaded as two CSV files below. One contains some limited participant information; the other all responses.
- Participants.
All columns from familiar and on are given on a scale of 1 to 5, with 1 being the worst/hardest/most unfamiliar and 5 being best/easiest/most familiar.
The background column is given as an integer, representing a 5-bit value. Their meaning per bit, from least to most significant bit:
- Math
- Computer science
- Human-computer interaction
- Visualization
- Other
- Responses.
The layout algorithms are given as 'A', 'B' and 'C', with the following mapping to the algorithms.
- Force-directed
- Polarized
- Bipartite
