Visualization of Dynamic Hierarchical Data
Hierarchies and trees are a very common data structure in many domains. For example, file systems are organized hierarchically, as well as websites, organizations, ontologies, etc. For visualizing such data, a number of visualization techniques are available (http://www.treevis.net). Often, such kinds of data structures also change over time (e.g. changes in an organigram, etc.). Despite, not many visualization techniques are available to represent changes in hierarchies over time.
The goal of this work is to conduct a structured state-of-the-art overview of available visualization techniques for dynamic hierarchical data, i.e. hierarchies that change over time.
