We use this approach generically for three applications: for visualization of data with geometric and categorical constraints, respectively.  ...  Given an initial graph layout which represents an association of the data, another set of constraints is applied to the graph to represent a second association on the same dataset to obtain the final layout  ...  The authors are grateful to a TeraGrid Resource Provider Grant for funding and the Visualization & Data Analysis Group, TACC for supporting this work.  ...

An energy-based model to optimize cluster visualization

Taoufiq Dkaki, Josiane Mothe
2014 2014 IEEE Eighth International Conference on Research Challenges in Information Science (RCIS)  
We propose an energy-based model for graph drawing that produces an esthetic drawing that ensures each cluster will occupy a separate zone within the visualization layout.  ...  Graphs capture the structure and thus help modeling a wide range of complex real-life data in various domains. Moreover graphs are especially suitable for information visualization.  ...  Eades [17] popularized one of the most used general drawing strategies -namely energy-based layout.  ...

In this paper, we present a novel approach that extends traditional force-based graph layouts to create an attribute-driven layout.  ...  They help us to understand the structure (topology) of the relational data. However in many real world data sets, additional (often multidimensional) attributes are attached to the network elements.  ...  Our main contribution is the extension of a force-based graph layout approach to act as an attribute-based layout system.  ...
