Challenging an institutionalized understanding of overview and detail as inherently opposed, the intention of this research is to develop a visualization method that accounts for the iconographic abundance of a collection and encourages its casual exploration. Expanding digitization efforts have led to a growing number of rich cultural heritage datasets that are successively being published online. At the same time scholars are exploring the potential of computational methods to expand the scale and scope of art history. In this context, data visualization is often equated with a distanced perspective diminishing the intricate and intriguing details of individual artifacts. In collaboration with a museum of applied and decorative arts, we have devised a novel interface concept for the exploration of image collections such as historical glass plate negatives. Inspired by photographic plates on a light table, the resulting Close-up Cloud translates the art historical method of close viewing into the digital by combining it with a dynamic representation of quantitative iconographic patterns across an entire image collection.}, subject = {Visualisierung}, language = {en} } @article{JungingerDoerk, author = {Junginger, Pauline and D{\"o}rk, Marian}, title = {Categorizing queer identities : an analysis of archival practices using the concept of boundary objects}, series = {Journal of Feminist Scholarship}, volume = {19}, journal = {Journal of Feminist Scholarship}, number = {19}, organization = {University of Massachusetts Dartmouth}, issn = {2158-6179}, doi = {10.23860/jfs.2021.19.05}, pages = {66 -- 79}, abstract = {In this paper, we present a field study that examines the development, application and maintenance of classification systems and controlled vocabularies in three archives documenting lesbian, trans* and queer-feminist histories. Queer archives face the challenge of documenting identities that are inherently characterized by embracing fluidity and ambiguity. Thus, queer identities are diametrically opposed to archival procedures of unambiguous classification. At the same time, queer activism relies partly on coherent identity categories in order to be able to act politically. We examine the pragmatic solutions that queer archives establish when dealing with tensions between those requirements. Our goal is to contribute to the ongoing discussions about the ethical dimensions of classification practices. Following the work of Geoffrey C. Bowker and Susan Leigh Star (1999) we use the concept of boundary objects as a central theoretical foundation of our research. This concept allows for tracing the negotiations and decision-making processes that influenced the creation of a specific classification system. Through conducting semi-structured interviews with staff members of queer archives in Germany we collected data about their efforts to archive the history of queer communities. Although there are initiatives developing metadata standards for queer identities, these standards are only used to a limited extent by the queer archives we examined. Rather, those archives established individual strategies for categorizing objects that are rooted in their specific history. We argue that classification systems and controlled vocabularies themselves can be understood as artifacts documenting the history of queer movements.}, subject = {LGBT}, language = {en} } @incollection{ScholzdaCostaOliveiraDoerk, author = {Scholz, Andrea and da Costa Oliveira, Thiago and D{\"o}rk, Marian}, title = {Infrastructure as digital tools and knowledge practices}, series = {Digitalisierung ethnologischer Sammlungen : Perspektiven aus Theorie und Praxis}, booktitle = {Digitalisierung ethnologischer Sammlungen : Perspektiven aus Theorie und Praxis}, publisher = {Transcript}, address = {Bielefeld}, isbn = {978-3-8376-5790-6}, issn = {2702-9026}, doi = {10.14361/9783839457900-017}, pages = {299 -- 315}, abstract = {Scholz, da Costa Oliveira und D{\"o}rk widmen sich in ihrem Beitrag Erfahrungen mit digitalen Werkzeugen im Kontext ethnologischer Sammlungen sowie den Herausforderungen, die sich bei der Ber{\"u}cksichtigung unterschiedlicher Wissenspraktiken in der Zusammenarbeit mit Heritage Communities stellen.

The overall aim behind this research was to devise visualizations that do justice to the material and semantic richness of an entire collection, while providing a casual mode of access that is inviting to people with no background in numismatics. To do this, we undertook an iterative design process, which involved a close collaboration with numismaticians and playful ideation with actual coins. Carefully negotiating expert knowledge and lay curiosity, the resulting visualization represents the collection's dimensions using thousands of thumbnails as visual data points. The coins can be arranged into various layouts such as piles representing, for example, metal types, or streams visualizing the ebb and flow of coins over the centuries. In the interface, one can play with the coins in a manner that would be unthinkable in a physical exhibition and that has not been tried in a digital display.

Previously, multi-dimensional models of emotion have been used rarely in visualizations of textual data, due to the perceptual challenges involved. Furthermore, until recently most text visualizations remained at a high level, precluding closer engagement with the deep semantic content of the text. Informed by empirical studies, we introduce a color mapping that translates any point in three-dimensional affective space into a unique color. Emosaic uses affective dictionaries of words annotated with the three emotional parameters of the valence-arousal-dominance model to extract emotional meanings from texts and then assigns to them corresponding color parameters of the hue-saturation-brightness color space. This approach of mapping emotion to color is aimed at helping readers to more easily grasp the emotional tone of the text. Several features of Emosaic allow readers to interactively explore the affective content of the text in more detail; e.g., in aggregated form as histograms, in sequential form following the order of text, and in detail embedded into the text display itself. Interaction techniques have been included to allow for filtering and navigating of text and visualizations.}, subject = {Mensch-Maschine-Kommunikation}, language = {en} } @article{KauerAkbabaDoerketal., author = {Kauer, Tobias and Akbaba, Derya and D{\"o}rk, Marian and Bach, Benjamin}, title = {Discursive Patinas}, series = {IEEE transactions on visualization and computer graphics}, volume = {21}, journal = {IEEE transactions on visualization and computer graphics}, number = {1}, publisher = {Institute of Electrical and Electronics Engineers (IEEE)}, address = {New York}, issn = {1077-2626}, doi = {10.1109/TVCG.2024.3456334}, pages = {1246 -- 1256}, abstract = {This paper presents discursive patinas, a technique to visualize discussions onto data visualizations, inspired by how people leave traces in the physical world. While data visualizations are widely discussed in online communities and social media, comments tend to be displayed separately from the visualization and we lack ways to relate these discussions back to the content of the visualization, e.g., to situate comments, explain visual patterns, or question assumptions. In our visualization annotation interface, users can designate areas within the visualization. Discursive patinas are made of overlaid visual marks (anchors), attached to textual comments with category labels, likes, and replies. By coloring and styling the anchors, a meta visualization emerges, showing what and where people comment and annotate the visualization. These patinas show regions of heavy discussions, recent commenting activity, and the distribution of questions, suggestions, or personal stories. We ran workshops with 90 students, domain experts, and visualization researchers to study how people use anchors to discuss visualizations and how patinas influence people's understanding of the discussion. Our results show that discursive patinas improve the ability to navigate discussions and guide people to comments that help understand, contextualize, or scrutinize the visualization.

In this context, we research the persuasive, emotional and memorable dimensions of data visualizations and illustrations in journalistic storytelling for long-form articles. We conducted a user study and compared the effects which data visualizations and illustrations have on changing attitude towards a presented topic. While visual representations are usually studied along one dimension, in this experimental study, we explore the effects on readers' attitudes along three: persuasion, emotion, and information retention. By comparing different versions of the same article, we observe how attitudes differ based on the visual stimuli present, and how they are perceived when combined. Results indicate that the narrative using only data visualization elicits a stronger emotional impact than illustration-only visual support, as well as a significant change in the initial attitude about the topic. Our findings contribute to a growing body of literature on how visual artifacts may be used to inform and influence public opinion and debate.

Data visualization has assumed a central role in environmental journalism and is often used in data stories to convey the dramatic consequences of climate change and other ecological crises. However, the emphasis on the catastrophic impacts of climate change tends to induce feelings of fear, anxiety, and apathy in readers. Climate mitigation, adaptation, and protection—all highly urgent in the face of the climate crisis—are at risk of being overlooked. These topics are more difficult to communicate as they are hard to convey on varying levels of locality, involve multiple interconnected sectors, and need to be mediated across various channels from the printed newspaper to social media platforms. So far, there has been little research on data visualization to enhance affective engagement with data about climate protection as part of solution-oriented reporting of climate change. With this research we characterize the unique challenges of constructive climate journalism for data visualization and share findings from a research and design study in collaboration with a national newspaper in Germany. Using the affordances and aesthetics of travel postcards, we present Klimakarten, a data journalism project on the progress of climate protection at multiple spatial scales (from national to local), across five key sectors (agriculture, buildings, energy, mobility, and waste), and for print and online use.

We propose 'unfolding of edges' as an interactive approach to integrate multivariate edge attributes dynamically into existing node-link diagrams.

This approach extends focus+context, semantic zoom, and animated transitions for network visualizations to accommodate edge details on-demand without cluttering the overall graph layout. We explore the design space for the unfolding of edges, which covers aspects of making space for the unfolding, of actually representing the edge context, and of navigating between edges. To demonstrate the utility of our approach, we present two case studies in the context of historical network analysis and computational social science.
