Topological Fisheye Views for Visualizing Large Graphs
Found in: IEEE Transactions on Visualization and Computer Graphics
By Emden R. Gansner, Yehuda Koren, Stephen C. North
Issue Date:July 2005
pp. 457-468
Graph drawing is a basic visualization tool that works well for graphs having up to hundreds of nodes and edges. At greater scale, data density and occlusion problems often negate its effectiveness. Conventional pan-and-zoom, multiscale, and geometric fish...
 
A C++ Data Model Supporting Reachability Analysis and Dead Code Detection
Found in: IEEE Transactions on Software Engineering
By Yih-Farn Chen, Emden R. Gansner, Eleftherios Koutsofios
Issue Date:September 1998
pp. 682-694
<p><b>Abstract</b>—A software repository provides a central information source for understanding and reengineering code in a software project. Complex reverse engineering tools can be built by analyzing information stored in the repositor...
 
A maxent-stress model for graph layout
Found in: Visualization Symposium, IEEE Pacific
By Emden R. Gansner,Yifan Hu,Stephen North
Issue Date:March 2012
pp. 73-80
In some applications of graph visualization, input edges have associated target lengths. Dealing with these lengths is a challenge, especially for large graphs. Stress models are often employed in this situation. However, the traditional full stress model ...
 
Multilevel agglomerative edge bundling for visualizing large graphs
Found in: 2011 IEEE Pacific Visualization Symposium (PacificVis)
By Emden R Gansner, Yifan Hu,Stephen North,Carlos Scheidegger
Issue Date:March 2011
pp. 187-194
Graphs are often used to encapsulate relationships between objects. Node-link diagrams, commonly used to visualize graphs, suffer from visual clutter on large graphs. Edge bundling is an effective technique for alleviating clutter and revealing high-level ...
 
Visualizing Graphs and Clusters as Maps
Found in: IEEE Computer Graphics and Applications
By Emden R Gansner, Yifan Hu,Stephen G Kobourov
Issue Date:November 2010
pp. 54-66
Information visualization is essential in making sense of large datasets. Often, high-dimensional data are visualized as a collection of points in 2D space through dimensionality reduction techniques. However, these traditional methods often don't capture ...
 
REportal: A Web-based Portal Site for Reverse Engineering
Found in: Reverse Engineering, Working Conference on
By Spiros Mancoridis, Timothy S. Souder, Yih-Farn Chen, Emden R. Gansner, Jeffrey L. Korn
Issue Date:October 2001
pp. 221
We present a web-based portal site for reverse engine ering software systems called Reportal. Re portal enables authorized users to upload their code to a secure web site and then, through the guide of wizards, browse and analyze their code. Currently the ...
 
Visualizing software for telecommunication services
Found in: Proceedings of the 2003 ACM symposium on Software visualization (SoftVis '03)
By Emden R. Gansner, John M. Mocenigo, Stephen C. North
Issue Date:June 2003
pp. 151-ff
An active research area in telecommunications concerns how to specify and control the addition of new services, such as call waiting or instant messaging, into existing software. One approach is to rely on a component-based architecture such as Distributed...
     
Uncluttering force-directed graph layouts
Found in: Proceedings of the fifteenth annual symposium on Computational geometry (SCG '99)
By Alejo Hausner, David P. Dobkin, Emden R. Gansner, Stephen C. North
Issue Date:June 1999
pp. 425-426
An interactive visualization of weighted three-dimensional α-hulls is presented for static and dynamic spheres. The α-hull is analytically computed and represented by a triangulated mesh. The entire surface is computed and displayed in real-time ...
