“…In contrast, existing approaches (Section 6) primarily rely on multiple views when visualizing multiple aspects of a system [1,17,30,31]. Although multi-view approaches can be very effective, users may also have considerable difficulty managing and navigating through dif- ferent views [27,28,32]. In our current research, we are particularly interested in whether these difficulties can be overcome by judicious rendering within a single view.…”

“…First, single-view illustrations avoid the difficulties when managing and navigating through different views [27,28,32]; secondly, they rapidly summarize a system because all information is available within that view; and thirdly, having one view helps different stakeholders to easily communicate different concerns within the same familiar picture. Single-view visualizations do not replace detailed stakeholder-specific visualizations.…”

Software is among the most complex human artifacts, and visualization is widely acknowledged as important to understanding software. In this paper, we consider the problem of understanding a software system's architecture through visualization. Whereas traditional visualizations use multiple stakeholder-specific views to present different kinds of taskspecific information, we propose an additional visualization technique that unifies the presentation of various kinds of architecture-level information, thereby allowing a variety of stakeholders to quickly see and communicate current development, quality, and costs of a software system. For future empirical evaluation of multi-aspect, single-view architectural visualizations, we have implemented our idea in an existing visualization tool, Vizz3D. Our implementation includes techniques, such as the use of a city metaphor, that reduce visual complexity in order to support single-view visualizations of large-scale programs.

“…Multiscale graph abstraction is another technique that preserves global structure, however navigation is difficult because clusters are explicitly contracted and expanded, e.g. [2,26]. Recent work combines these two approaches with topological fisheye views to reduce the number of displayed nodes while preserving the network structure [14].…”

Balancing Systematic and Flexible Exploration of Social Networks

Abstract-Social network analysis (SNA) has emerged as a powerful method for understanding the importance of relationships in networks. However, interactive exploration of networks is currently challenging because: (1) it is difficult to find patterns and comprehend the structure of networks with many nodes and links, and (2) current systems are often a medley of statistical methods and overwhelming visual output which leaves many analysts uncertain about how to explore in an orderly manner. This results in exploration that is largely opportunistic. Our contributions are techniques to help structural analysts understand social networks more effectively. We present SocialAction, a system that uses attribute ranking and coordinated views to help users systematically examine numerous SNA measures. Users can (1) flexibly iterate through visualizations of measures to gain an overview, filter nodes, and find outliers, (2) aggregate networks using link structure, find cohesive subgroups, and focus on communities of interest, and (3) untangle networks by viewing different link types separately, or find patterns across different link types using a matrix overview. For each operation, a stable node layout is maintained in the network visualization so users can make comparisons. SocialAction offers analysts a strategy beyond opportunism, as it provides systematic, yet flexible, techniques for exploring social networks.

“…However, several authors think that larger graph structures can be viewed in 3D (Parker et al (1998)). In the empirical study of Ware & Franck (1996), which measured path-tracing ability in 3D graphs, they suggested that the amount of information that can be displayed in 3D with stereoscopic and motion depth cues exceeds 2D representations by a factor of 3.…”
