Reaction: Task Taxonomy for Graph Visualization

This paper lists the tasks for graph visualization to be followed for comparing and improving such systems. It divides the tasks into specific groups and creates a taxonomy of operations, useful for analysis of graphs. The authors first explain the basic low-level components of graphs like the node, the links and graphs. These tasks can be classified into Topology-Based Tasks, Attribute Based Tasks, Browsing Tasks and Overview Tasks. The examples provided are very easy and makes understanding these classifications easier. Further, they list high-level tasks which are complex and cannot be categorized by any of the mentioned types. This division can be used to characterize tools which visualize graphs. This paper would be very helpful for amateurs but lacks details about the research, or how such tasks were come up with. The scope of the paper seems limited and it would have been better if some graphics were included to aid in understanding the concepts.
