Deliverables and benefits
Problem statement
Open-source Java graph-visualization toolkit with a modular
architecture
Graph visualization/exploration is hard!
The following factors raise the
complexity of the task:
• Internal data structure from 1st principles to represent
arbitrary graphs
• Graphs often contain large
amounts of metadata
• Separable concerns: loaders, mapping providers, and
exporters
Image
• Hairball Effect: With
increasing complexity,
graph turns into “hairball”
Thrust area: New Design
Paradigms and Processes
Project type: Current
Image
Percent complete: 66%
IAB funds: 50%
Other funds: 50% - some
other research grant
• Flexibility to define mappings of node and edge attributes
to visual markers

Users of the results of this project:
Approach and method
Image
Image
Flexible input format support
Image
Image
• Researchers doing human-subject experiments with graphs,
specifically ontologies
• Developers of applications with graph-visualization
components
• E.g., GraphML, OWL, …
Use of access metrics (frequency of query, etc.):
Flexible output format support
Image
• E.g., X3D, OpenGL, …
• Can be stored in metadata and mapped to visual property
Project plan
Fall 2012:
Abstraction of Mappings
Image
• Allows for domain-specific
visualization
Images
• OWL File Loader v1
Images
Images
• X3D Solar layout mapping v1
Spring 2013: User studies and evaluations

Current state of practice and research
Many traditional toolkits to choose from, but:
• Limited input format support
• Limited output format support
