AdaptiviTree: Adaptive Tree Visualization for Tournament-Style Brackets

D.S. Tan, G. Smith, Bongshin Lee, G.G. Robertson
2007 IEEE Transactions on Visualization and Computer Graphics  
In this paper, we present AdaptiviTree, a novel visualization that adaptively deforms the representation of the tree and uses its shape to convey outcome information.  ...  The classic bracket visualization was designed for use on paper and utilizes an incrementally additive system in which the winner of each match-up is rewritten in the next round as the tournament progresses  ...  This is in contrast to earlier work on visualizing hierarchy changes over time with a timeline, which requires sequential viewing of the state of the tree at specific time periods.  ...

Cartesian vs. Radial – A Comparative Evaluation of Two Visualization Tools [chapter]

Michael Burch, Felix Bott, Fabian Beck, Stephan Diehl
2008 Lecture Notes in Computer Science  
In this work we compare a radial and a Cartesian variant of a visualization tool for sequences of transactions in information hierarchies.  ...  The Timeline Trees (TLT) approach uses a Cartesian coordinate system to represent both the hierarchy and the sequence of transactions whereas the TimeRadarTrees (TRT) technique is the radial counterpart  ...  In the following we explain the details of the two tools compared in the study: Timeline Trees (TLT) [18] which uses a Cartesian representation to visualize sequences of transactions in an information  ...

Machine-Aware Atomic Broadcast Trees for Multicores

Stefan Kaestle, Reto Achermann, Roni Haecki, Moritz Hoffmann, Sabela Ramos, Timothy Roscoe
2016 USENIX Symposium on Operating Systems Design and Implementation  
Experiments on a wide variety of multicore machines show that near-optimal tree topologies and communication patterns are highly machine-dependent, but can nevertheless be derived by Smelt and often further  ...  The performance of parallel programs on multicore machines often critically depends on group communication operations like barriers and reductions being highly tuned to hardware, a task requiring considerable  ...  Acknowledgments We thank our mentor Peter Chen and the anonymous reviewers for their detailed and useful reviews and the Computer Architecture Group from the University of A Coruña for the access to their  ...

A Survey of Approaches for Event Sequence Analysis and Visualization using the ESeVis Framework [article]

Anton Yeshchenko, Jan Mendling
2022 arXiv   pre-print
In this paper, we develop the Event Sequence Visualization framework (ESeVis) that gives due credit to the traditions of both fields.  ...  The variety of application areas explains that techniques for event sequence data analysis have been developed rather independently in different fields of computer science.  ...  Hierarchy Visualization Hierarchy visualizations are graph-based event sequence visualizations that use a tree topology.  ...

Visual Analysis of High-Dimensional Event Sequence Data via Dynamic Hierarchical Aggregation

David Gotz, Jonathan Zhang, Wenyuan Wang, Joshua Shrestha, David Borland
2019 IEEE Transactions on Visualization and Computer Graphics  
The approach leverages a predefined hierarchy of dimensions to computationally quantify the informativeness, with respect to a measure of interest, of alternative levels of grouping within the hierarchy  ...  This information is then interactively visualized, enabling users to dynamically explore the hierarchy to select the most appropriate level of grouping to use at any individual step within an analysis.  ...  ACKNOWLEDGMENTS The research reported in this article was supported in part by a grant from the National Science Foundation (#1704018).  ...

2014 IEEE Transactions on Visualization and Computer Graphics  
Abstract-We present FluxFlow, an interactive visual analysis system for revealing and analyzing anomalous information spreading in social media.  ...  The challenge is rooted in data analysts' capability of discerning the anomalous information behaviors, such as the spreading of rumors or misinformation, from the rest that are more conventional patterns  ...  First, to accommodate the navigation of large hierarchies, we developed a compact visual representation of tree branches based on the visualization proposed by Zhao et al. [48] .  ...
