AI-Centered Grand Challenges in Visual Analytics for Healthcare: Synthesizing the VAHC 2025 Community Experience
Jürgen Bernard, David Gotz, Robert S Laramee +4
The intersection of AI, healthcare, and visualization is evolving rapidly, posing challenges that cut across disciplinary boundaries and resist easy resolution. The Visual Analytic…
A Heuristic Approach for Dual Expert/End-User Evaluation of Guidance in Visual Analytics
Davide Ceneda, Christopher Collins, Mennatallah El-Assady +3
Guidance can support users during the exploration and analysis of complex data. Previous research focused on characterizing the theoretical aspects of guidance in visual analytics…
TimeLighting: Guided Exploration of 2D Temporal Network Projections
Velitchko Filipov, Davide Ceneda, Daniel Archambault +1
In temporal ( event-based ) networks, time is a continuous axis, with real-valued time coordinates for each node and edge. Computing a layout for such graphs means embedding the no…
On Time and Space: An Experimental Study on Graph Structural and Temporal Encodings
Velitchko Filipov, Alessio Arleo, Markus Bögl +1
Dynamic networks reflect temporal changes occurring to the graph's structure and are used to model a wide variety of problems in many application fields. We investigate the design…
Egocentric Network Exploration for Immersive Analytics
Johannes Sorger, Alessio Arleo, Peter Kán +2
To exploit the potential of immersive network analytics for engaging and effective exploration, we promote the metaphor of "egocentrism", where data depiction and interaction are a…
VAIM: Visual Analytics for Influence Maximization
Alessio Arleo, Walter Didimo, Giuseppe Liotta +2
In social networks, individuals' decisions are strongly influenced by recommendations from their friends and acquaintances. The influence maximization (IM) problem asks to select a…
Immersive Analytics of Large Dynamic Networks via Overview and Detail Navigation
Johannes Sorger, Manuela Waldner, Wolfgang Knecht +1
Analysis of large dynamic networks is a thriving research field, typically relying on 2D graph representations. The advent of affordable head mounted displays however, sparked new…
Sabrina: Modeling and Visualization of Economy Data with Incremental Domain Knowledge
Alessio Arleo, Christos Tsigkanos, Chao Jia +7
Investment planning requires knowledge of the financial landscape on a large scale, both in terms of geo-spatial and industry sector distribution. There is plenty of data available…
GiViP: A Visual Profiler for Distributed Graph Processing Systems
Alessio Arleo, Walter Didimo, Giuseppe Liotta +1
Analyzing large-scale graphs provides valuable insights in different application scenarios. While many graph processing systems working on top of distributed infrastructures have b…
A Distributed Multilevel Force-directed Algorithm
Alessio Arleo, Walter Didimo, Giuseppe Liotta +1
The wide availability of powerful and inexpensive cloud computing services naturally motivates the study of distributed graph layout algorithms, able to scale to very large graphs.…
Visibility Representations of Boxes in 2.5 Dimensions
Alessio Arleo, Carla Binucci, Emilio Di Giacomo +7
We initiate the study of 2.5D box visibility representations (2.5D-BR) where vertices are mapped to 3D boxes having the bottom face in the plane and edges are unobstructed li…
A Distributed Force-Directed Algorithm on Giraph: Design and Experiments
Alessio Arleo, Walter Didimo, Giuseppe Liotta +1
In this paper we study the problem of designing a distributed graph visualization algorithm for large graphs. The algorithm must be simple to implement and the computing infrastruc…
