Reaction: Task Taxonomy for Graph Visualization

Until now I thought that making visualizations was an artistic task. Not entirely true, but I never saw or thought about the procedure as a fixed list of tasks. The artistic component and subjective appreciation of visualizations make it hard to measure and evaluate. The authors provide a taxonomy, benchmark datasets, and specific tasks that would help both designers and evaluators.

The idea is to break this tasks into lower level tasks, and for this the authors add two general tasks to those purposed by Amal et al. Tasks are grouped in four groups: topology-based, attribute-based, browsing and overview tasks.

General descriptions and examples are given for each task.
