ABSTRACT
Visualizations can help amplify human cognition. In an era where networks are becoming increasingly complex, the desirability of tools to compare and contrast sets, relationships, and reach is significant. Motivated by a practical need articulated by corporate decision makers, this research presents our journey in designing and implementing bicentric diagrams, a novel graph-based set visualization technique. A bicentric diagram enables simultaneous identification of sets, set relationships, and set member reach in integrated egonetworks of two focal entities. Our technique builds on the well-established theory of tie strength to visually group and position nodes. We illustrate the applicability of bicentric diagrams with an example from technology co-occurrence in press releases. We assess the value of our technique using an expert-based value-driven evaluation approach.

Bicentric diagrams
In an era where data on social, economic, and physical networks are proliferating at a rapid pace, the ability to understand the underlying complex structural connections, discover prominent entities, and identify clusters is becoming increasingly ...
Untangling Euler Diagrams
In many common data analysis scenarios the data elements are logically grouped into sets. Venn and Euler style diagrams are a common visual representation of such set membership where the data elements are represented by labels or glyphs and sets are ...
Countering Security Information Overload through Alert and Packet Visualization
When given the task of securing a network, security analysts and network administrators typically face large volumes of security data that demand analysis. Selectively mapping elements of these flows to carefully crafted graphical displays can provide ...
