Categorising tasks is a common pursuit in the visualisation research community, with a wide variety of taxonomies, typologies, design spaces, and frameworks having been develo...

Using a task classification in the visualisation design process for task understanding and abstraction: an empirical study

Conference Proceeding
Kerracher, N., Kennedy, J., & Chalmers, K. (2018)
Using a task classification in the visualisation design process for task understanding and abstraction: an empirical study. In J. Johansson, F. Sadlo, & T. Schreck (Eds.), Proceedings of the 2018 Eurographics Conference on Visualization (EuroVis 2018) - Short Papers, (79-83). https://doi.org/10.2312/eurovisshort.20181082
Task classifications are widely purported to be useful in the design process, with various suggestions having been made for their use at the different stages. However, little ...

Pathways for Theoretical Advances in Visualization

Pathways for Theoretical Advances in Visualization. IEEE Computer Graphics and Applications, 37(4), 103-112. https://doi.org/10.1109/MCG.2017.3271463
There is little doubt that having a theoretic foundation will benefit the field of visualization, including its main subfields: information visualization, scientific visualiza...

MLCut: exploring multi-level cuts in dendrograms for biological data

Conference Proceeding
Vogogias, A., Kennedy, J., Archambault, D., Anne Smith, V., & Currant, H. (2016)
MLCut: exploring multi-level cuts in dendrograms for biological data. In C. Turkay, & T. Ruan Wan (Eds.), Computer Graphics and Visual Computing (CGVC)https://doi.org/10.2312/cgvc.20161288
Choosing a single similarity threshold for cutting dendrograms is not sufficient for performing hierarchical clustering analysis of heterogeneous data sets. In addition, alter...

Telling stories about dynamic networks with graph comics.

Conference Proceeding
Bach, B., Kerracher, N., Hall, K. W., Carpendale, S., Kennedy, J., & Henry Riche, N. (2016)
Telling stories about dynamic networks with graph comics. In Proceedings of the ACM Conference on Human Factors in Computing Systems (CHI'16), (1-13). https://doi.org/10.1145/2858036.2858387
In this paper, we explore graph comics as a medium to communicate changes in dynamic networks. While previous research has focused on visualizing dynamic networks for data exp...

Hierarchical Clustering with Multiple-Height Branch-Cut Applied to Short Time-Series Gene Expression Data

Conference Proceeding
Vogogias, A., Kennedy, J., & Archambault, D. (2016)
Hierarchical Clustering with Multiple-Height Branch-Cut Applied to Short Time-Series Gene Expression Data. In T. Isenberg, & F. Sadlo (Eds.), EuroVis 2016 - Posters. , (1-3). https://doi.org/10.2312/eurp.20161127
Rigid adherence to pre-specified thresholds and static graphical representations can lead to incorrect decisions on merging of clusters. As an alternative to existing automate...

A Task Taxonomy for Temporal Graph Visualisation

Journal Article
Kerracher, N., Kennedy, J., & Chalmers, K. (2015)
A Task Taxonomy for Temporal Graph Visualisation. IEEE Transactions on Visualization and Computer Graphics, 21(10), 1160-1172. https://doi.org/10.1109/tvcg.2015.2424889
By extending and instantiating an existing formal task framework, we define a task taxonomy and task design space for temporal graph visualisation. We discuss the process invo...
