2D 3D Visualisation Creation

This visualisation shows the raw number of visualisations created which were:

1. 2D only

2. 2D with additional visual channel (e.g. size, colour)

3. 3D only

4. 3D with additional visual channel

The aim of this visualisation was to see if participants favoured 2D or 3D, and if they used the third z-dimension instead of the additional visual channel for 2D. Note that this metric is specifically for visualisations that were torn out from the panel—it does not account for instances where a participant "works" off a visualisation on a panel for an extended period of time without tearing it out.

This visualisation only exists for Part B.

There are a few interesting things of note in this visualisation:

• Participants created much more 3D visualisations as a whole than 2D visualisations. However, this is likely a byproduct of the authoring panel interface requiring 3D visualisations be torn out in order to rotate them.

• Some participants didn't create any visualisations at all for certain tasks. This was for two probable reasons: they were working together with their team for the entire task, such as G7, or they simply decided not to tear out visualisations.

P25 created an unusually large number of visualisations in FET, however this was due to him playing around at the very end of the study.

Code

Based on ActionData and ObjectData.

We needed to stitch together when participants created visualisations, and lookup in these instances the visual properties of said visualisations. This is to tally up the number of occurrences between 2D and 3D visualisations:

Then we plot using ggplot2 for the manuscript version:
