Exploring Hierarchical Visualization Designs Using Phylogenetic Trees

by Shaomeng Lia, R. Jordan Crouserb, Garth Griffinb, Connor Gramazioc, Hank Childsa, Remco Changb
"... Ongoing research on information visualization has produced an ever-increasing number of visualization designs. Despite this activity, limited progress has been made in categorizing this large number of information visual-izations. This makes understanding their common design features challenging, an ..."

, and obscures the yet unexplored areas of novel designs. With this work, we provide categorization from an evolutionary perspective, leveraging a computational model to represent evolutionary processes, the phylogenetic tree. The result — a phylogenetic tree of a design corpus of hierarchical visualizations

Arb: A software environment for sequence data

by Wolfgang Ludwig, Oliver Strunk, Ralf Westram, Lothar Richter, Harald Meier, Arno Buchner, Tina Lai, Wolfram Foè Rster, Igor Brettske, Stefan Gerber, Anton W. Ginhart, Oliver Gross, Silke Grumann, Stefan Hermann, Ralf Jost, Andreas Koè Nig, Thomas Liss, Ralph Luè Ûmann, Michael May, Bjoè Rn Nonhoff, Boris Reichel, Robert Strehlow, Ros Stamatakis, Norbert Stuckmann, Er Vilbig, Michael Lenke, Thomas Ludwig, Arndt Bode - Nucleic Acids Res , 2004
"... The ARB (from Latin arbor, tree) project was initiated almost 10 years ago. The ARB program package comprises a variety of directly interacting software tools for sequence database maintenance and analysis which are controlled by a common graphical user interface. Although it was initially designed ..."

phylogenetic tree visualized in the main window can be used for data access and visualization. The package comprises additional tools for data import and export, sequence alignment, primary and secondary structure editing, pro-®le and ®lter calculation, phylogenetic analyses, speci®c hybridization probe design

Octrees for faster isosurface generation

by Jane Wilhelms, Allen Van Gelder - IEEE TRANSACTIONS ON MEDICAL IMAGING , 2000
"... The large size of many volume data sets often prevents visualization algorithms from providing interactive rendering. The use of hierarchical data structures can ameliorate this problem by storing summary information to prevent useless exploration of regions of little or no current interest within ..."

TreeJuxtaposer: scalable tree comparison using Focus+Context with guaranteed visibility

by Tamara Munzner, François Guimbretière - ACM Transactions on Graphics , 2003
"... Structural comparison of large trees is a difficult task that is only partially supported by current visualization techniques, which are mainly designed for browsing. We present TreeJuxtaposer, a system designed to support the comparison task for large trees of several hundred thousand nodes. We int ..."

fluid exploration experience that scales both in the size of the dataset and the number of pixels in the display. We have based the design decisions for our system on the needs of a target audience of biologists who must understand the structural details of many phylogenetic, or evolutionary, trees. Our

AWTY (Are We There Yet?): a system for graphical exploration of MCMC convergence in Bayesian phylogenetics

by Johan A. A. Nylander, James C. Wilgenbusch , Dan L. Warren , David L. Swofford , 2007
"... Summary: A key element to a successful Markov chain Monte Carlo (MCMC) inference is the programming and run performance of the Markov chain. However, the explicit use of quality assessments of the MCMC simulations—convergence diagnostics—in phylogenetics is still uncommon. Here we present a simple t ..."
Abstract - Cited by 108 (5 self) - Add to MetaCart
tool that uses the output from MCMC simulations and visualizes a number of properties of primary interest in a Bayesian phylogenetic analysis, such as convergence rates of posterior split probabilities and branch lengths. Graphical exploration of the output from phylogenetic MCMC simulations gives

Data Exploration with Paired Hierarchical Visualizations: Initial Designs of PairTrees

by Bill Kules, Bill Kules, Ben Shneiderman, Ben Shneiderman, Catherine Plaisant, Catherine Plaisant , 2003
"... Paired hierarchical visualizations (PairTrees) integrate treemaps, node-link diagrams, choropleth maps and other information visualization techniques to support exploration of hierarchical data sets at multiple levels of abstraction. This paper describes several novel applications of PairTrees in th ..."

Treevolution: visual analysis of phylogenetic trees

by Rodrigo Santamaría, Roberto Therón - Bioinformatics , 2009
"... Summary: Treevolution is a tool for the representation and exploration of phylogenetic trees that facilitates visual analysis. There are several useful tools to visualize phylogenetic trees, but their level of interaction is usually low, especially in the case of radial representations. Highly inter ..."

"... InfoSky is a system enabling users to explore large, hierarchically structured document collections. Similar to a real-world telescope, InfoSky employs a planar graphical representation with variable magnification. Documents of similar content are placed close to each other and are visualised as sta ..."
