Trees in a treemap: visualizing multiple hierarchies

Michael Burch, Stephan Diehl, Robert F. Erbacher, Jonathan C. Roberts, Matti T. Gröhn, Katy Börner
2006 Visualization and Data Analysis 2006  
We introduce a new visualization technique that we call Trees In A Treemap. In this visualization edges can either be drawn as straight or orthogonal edges.  ...  This paper deals with the visual representation of a particular kind of structured data: trees where each node is associated with an object (leaf node) of a taxonomy.  ...  Several internet routes from the same host drawn in a fully expanded hierarchy of IP addresses Robertson 15 uses animation to show multiple hierarchies and connect single hierarchy nodes with links.  ...

Hybrid-Treemap Layouting [article]

Sebastian Hahn, Jürgen Döllner
2017 Eurographics Conference on Visualization  
This paper presents an approach for hybrid treemaps, which applies and combines several different layout principles within a single tree map in contrast to traditional treemap variants based on a single  ...  Based on a number of identified edge cases, we propose a combination of these different layout algorithms, individually selected for and applied on each sub hierarchy of the given treemap data.  ...  any sub-hierarchies (leafs only), or every sub-hierarchy is also layouted as a Voronoi treemap.  ...

ACKNOWLEDGMENTS The authors would like to thank Michel Westenberg for participating in our expert review.  ...  In general, we may derive uncertainty from temporal variation of a numerical value. Uncertainty Treemaps can then straightforwardly visualize temporally varying data in a static hierarchy.  ...  in the hierarchy.  ...

Edge Equalized Treemaps

Aimi Kobayashi, Kazuo Misue, Jiro Tanaka
2012 2012 16th International Conference on Information Visualisation  
Treemap is a visualization method for hierarchical structures in which nodes are drawn as rectangles and arranged in a nested style.  ...  In this paper, we propose an Edge Equalized Treemap, a representation that embeds visual data such as a bar chart in leaf rectangles.  ...  Originally, Treemaps represented trees where each leaf node had only one weight. However, there are trees in which leaf nodes have multiple data and time-series data.  ...

Progressive Presentation of Large Hierarchies Using Treemaps [chapter]

René Rosenbaum, Bernd Hamann

Using Treemaps to Visualize Phylogenetic Trees [chapter]

2005 Lecture Notes in Computer Science  
In addition, we propose a hybrid tree/treemap representation which provides a detailed view of subtrees via treemaps while maintaining a contextual view of the entire topology at the same time.  ...  However, it is difficult to extract the valuable information contained in those large trees without appropriate visualization tools.  ...  Usually, a multiple alignment of a-in a biological context-suitable small region of their DNA or protein sequences can be used as input for the computation of phylogenetic trees.  ...
