Aggregated Dendrograms for Visual Comparison Between Many Phylogenetic Trees

The Aggregated Dendrogram project is a collaboration between PhD student Zipeng Liu and DFP faculty member (CS) Tamara Munzner, and Bioinformatics PhD student Shing Hei Zhan,  in consultation with UBC colleagues Sean Graham, Sarah Otto, and Wayne Maddison in the Biodiversity Research Centre. Aggregated Dendrograms are a new visualization technique designed for the visual comparison of multiple phylogenetic trees in evolutionary biology, to help biologists look for supporting or conflicting evidence for hypotheses that require inspection of both topological structure and attribute values at different levels of detail in a collection of hundreds of trees.  Aggregated dendrograms concisely summarize the topological relationships between interactively chosen focal subtrees according to biologically meaningful criteria. The ADView tool is built around an implementation of aggregated dendrograms with a layout algorithm that automatically adapts to the available screen space. This paper is now published.
