Hierarchical-temporal data visualization using a Tree-ring Metaphor

Abstract

This paper describes a novel and efficient visualization technique intended for hierarchical-temporal data using a tree-ring like layout. Hierarchies with time appear in numerous fields such as genealogy, evolution taxonomies or time lines. In many cases, state-of-the-art static diagrams are produced in these fields. By using several information visualization strategies, such as focus + context, the tree-ring approachhas the ability to visualize and navigate these, potentially complex, hierarchies trough time. This way a deeper insight into the problem at hand can be gained.
