    Open Your Ears and Take a Look: A State-of-the-Art Report on the Integration of Sonification and Visualization
    (The Eurographics Association and John Wiley & Sons Ltd., 2024) Enge, Kajetan; Elmquist, Elias; Caiola, Valentina; Rönnberg, Niklas; Rind, Alexander; Iber, Michael; Lenzi, Sara; Lan, Fangfei; Höldrich, Robert; Aigner, Wolfgang; Garth, Christoph; Kerren, Andreas; Raidou, Renata
    The research communities studying visualization and sonification for data display and analysis share exceptionally similar goals, essentially making data of any kind interpretable to humans. One community does so by using visual representations of data, and the other community employs auditory (non-speech) representations of data. While the two communities have a lot in common, they developed mostly in parallel over the course of the last few decades. With this STAR, we discuss a collection of work that bridges the borders of the two communities, hence a collection of work that aims to integrate the two techniques into one form of audiovisual display, which we argue to be ''more than the sum of the two.'' We introduce and motivate a classification system applicable to such audiovisual displays and categorize a corpus of 57 academic publications that appeared between 2011 and 2023 in categories such as reading level, dataset type, or evaluation system, to mention a few. The corpus also enables a meta-analysis of the field, including regularly occurring design patterns such as type of visualization and sonification techniques, or the use of visual and auditory channels, showing an overall diverse field with different designs. An analysis of a co-author network of the field shows individual teams without many interconnections. The body of work covered in this STAR also relates to three adjacent topics: audiovisual monitoring, accessibility, and audiovisual data art. These three topics are discussed individually in addition to the systematically conducted part of this research. The findings of this report may be used by researchers from both fields to understand the potentials and challenges of such integrated designs while hopefully inspiring them to collaborate with experts from the respective other field.

    The State of the Art in Visual Analytics for 3D Urban Data
    (The Eurographics Association and John Wiley & Sons Ltd., 2024) Miranda, Fabio; Ortner, Thomas; Moreira, Gustavo; Hosseini, Maryam; Vuckovic, Milena; Biljecki, Filip; Silva, Claudio T.; Lage, Marcos; Ferreira, Nivan; Garth, Christoph; Kerren, Andreas; Raidou, Renata
    Urbanization has amplified the importance of three-dimensional structures in urban environments for a wide range of phenomena that are of significant interest to diverse stakeholders. With the growing availability of 3D urban data, numerous studies have focused on developing visual analysis techniques tailored to the unique characteristics of urban environments. However, incorporating the third dimension into visual analytics introduces additional challenges in designing effective visual tools to tackle urban data's diverse complexities. In this paper, we present a survey on visual analytics of 3D urban data. Our work characterizes published works along three main dimensions (why, what, and how), considering use cases, analysis tasks, data, visualizations, and interactions. We provide a fine-grained categorization of published works from visualization journals and conferences, as well as from a myriad of urban domains, including urban planning, architecture, and engineering. By incorporating perspectives from both urban and visualization experts, we identify literature gaps, motivate visualization researchers to understand challenges and opportunities, and indicate future research directions.

    State of the Art of Graph Visualization in non-Euclidean Spaces
    (The Eurographics Association and John Wiley & Sons Ltd., 2024) Miller, Jacob; Bhatia, Dhruv; Kobourov, Stephen; Garth, Christoph; Kerren, Andreas; Raidou, Renata
    Visualizing graphs and networks in non-Euclidean space can have benefits such as natural focus+context in hyperbolic space and the familiarity of interactions in spherical space. Despite work on these topics going back to the mid 1990s, there is no survey, or a part of a survey for this area of research. In this paper we review and categorize over 60 relevant papers and analyze them by geometry, (e.g., spherical, hyperbolic, torus), by contribution (e.g., technique, evaluation, proof, application), and by graph class (e.g., tree, planar, complex).

    A Systematic Literature Review of User Evaluation in Immersive Analytics
    (The Eurographics Association and John Wiley & Sons Ltd., 2024) Friedl-Knirsch, Judith; Pointecker, Fabian; Pfistermüller, Sandra; Stach, Christian; Anthes, Christoph; Roth, Daniel; Garth, Christoph; Kerren, Andreas; Raidou, Renata
    User evaluation is a common and useful tool for systematically generating knowledge and validating novel approaches in the domain of Immersive Analytics. Since this research domain centres around users, user evaluation is of extraordinary relevance. Additionally, Immersive Analytics is an interdisciplinary field of research where different communities bring in their own methodologies. It is vital to investigate and synchronise these different approaches with the long-term goal to reach a shared evaluation framework. While there have been several studies focusing on Immersive Analytics as a whole or on certain aspects of the domain, this is the first systematic review of the state of evaluation methodology in Immersive Analytics. The main objective of this systematic literature review is to illustrate methodologies and research areas that are still underrepresented in user studies by identifying current practice in user evaluation in the domain of Immersive Analytics in coherence with the PRISMA protocol.
