A Task Taxonomy for Temporal Graph Visualisation (2015)
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 involved in their generation, and describe how the design space can be ‘sliced... Read More about A Task Taxonomy for Temporal Graph Visualisation.
