Timeline trees
2008
Proceedings of the working conference on Advanced visual interfaces - AVI '08
Preserved Fulltext
In this paper we present a novel method for visualizing sequences of these kinds of transactions in information hierarchies. ...
It uses a tree layout to draw the hierarchy and a timeline to represent progression of transactions in the hierarchy. ...
CONCLUSIONS We have introduced Timeline Trees as a visualization technique to explore sequences of transactions in information hierarchies. ...

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. ...

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 ...

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. ...
