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. The findings from quantitative and qualitative analysis of reader feedback confirm our overall approach and suggest implications for future work.}, subject = {Erz{\"a}hlen}, language = {en} } @inproceedings{deGuentherNanniKyriazisetal., author = {de G{\"u}nther, Sabine and Nanni, Giacomo and Kyriazis, Ilias and Freyberg, Linda and D{\"o}rk, Marian}, title = {Tracing and Telling}, series = {EVA BERLIN 2023}, booktitle = {EVA BERLIN 2023}, editor = {Lengyel, Dominik and Bienert, Andreas}, address = {Cottbus}, organization = {Brandenburgische Technische Universit{\"a}t Cottbus-Senftenberg (BTU)}, isbn = {978-3-88609-891-0}, pages = {333 -- 338}, abstract = {Cultural collections have transcended the boundaries of physical showcases and storage cabinets, evolving into intricate digital webs of interconnected data.

Even though edges are the constitutive elements of networks, there have been only few attempts to visualize attributes of edges. In this work, we focus on the critical importance of edge attributes for interpreting network visualizations and building trust in the underlying data. We propose 'unfolding of edges' as an interactive approach to integrate multivariate edge attributes dynamically into existing node-link diagrams. Unfolding edges is an in-situ approach that gradually transforms basic links into detailed representations of the associated edge attributes. 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. For these, web-based prototypes were implemented based on which we conducted interviews with domain experts. The experts' feedback suggests that the proposed unfolding of edges is a useful tool for exploring rich edge information of multivariate graphs.}, subject = {Visualisierung}, language = {en} } @inproceedings{BludauHallingHollyetal., author = {Bludau, Mark-Jan and Halling, Thorsten and Holly, Eva Maria and Wieloch, Jasmin and Schnaitter, Hannes and Balck, Sandra and Plakidis, Melina and Rehm, Georg and Fangerau, Heiner and D{\"o}rk, Marian}, title = {Was sehe ich?

Theoretically, interactivity is often described as the means to support analytical tasks, while in practice, it encompasses the techniques that alter visual representations. These notions are a useful starting point to study the role of interactivity in critical engagements with data visualizations. At the core of critical interactivity is the negotiation of authority and agency: authority as authors provide structure and context, and agency as viewers navigate and interpret the data on their own terms. This raises the critical question: who has the power to control the visualization? Drawing from four case studies in science communication, art history, anthropology, and climate advocacy, we examine how critical interactivity links exploration and narration. We reflect on the effort involved in preparing data and propose design strategies for implementing critical interactivity in data visualization.}, subject = {Interaktive Medien}, language = {en} }
