This folder contains the experimental images used in the empirical studies reported in: "The Turing Test for Graph Drawing Algorithms", by Helen C. Purchase, Daniel Archambault, Stephen Kobourov, Martin Nollenburg, Sergey Pupyrev and Hsiang-Yun Wu. In Proceedings of the Graph Drawing Conference, September 2020.

Note:  We note, in retrospect, that the orthogonal version of Graph 2 is incorrect. We are confident that, given the extent of our data (4364 data points) and stimuli (108 drawings), this error does not affect our overall results or conlusions. We have reconfirmed that all other stimuli are correct.
