The resulting visual appearance can be characterized as a map network consisting of visited places and their connections. The visited places are shown as circular map extracts scaled according to the time spent there and the movements between the places are represented as edges between the places. A key feature of the Shifted Maps visualization is the possibility to explore the data in three different arrangements based on geo-spatial position, travel time, and frequency of movements. By combining map and network visualizations of movement data, it becomes possible to analyze and compare spatial and temporal topologies.}, subject = {Geographie}, language = {en} } @article{AlbrechtDoerkMueller, author = {Albrecht, Kim and D{\"o}rk, Marian and M{\"u}ller, Boris}, title = {Culturagraphy}, series = {Leonardo}, volume = {50}, journal = {Leonardo}, number = {2}, publisher = {MIT Press}, address = {Cambridge, Mass.}, issn = {1530-9282}, doi = {10.1162/LEON_a_01230}, pages = {209 -- 210}, abstract = {Culturegraphy visualizes the exchange of cultural information over time.

All findings reported in this article were made through a process that involved network scientists, a media theorist and a sociologist; the role that visualization can play in bridging scientific communities was central to this work. The visualizations were in fact the result of a process to bring researchers from different disciplines together. While traditionally physicists have used different methods than those used by media theorists or sociologists, physicists are increasingly asking questions similar to those asked by media theorists or sociologists as they study the dynamics in networks. Visualization can serve as a common language that brings fields together and identifies the differences between them but that also has its own idiosyncratic views.}, subject = {Graphische Datenverarbeitung}, language = {en} } @article{StahnkeDoerkMuelleretal., author = {Stahnke, Julian and D{\"o}rk, Marian and M{\"u}ller, Boris and Thom, Andreas}, title = {Probing Projections}, series = {IEEE transactions on visualization and computer graphics}, volume = {22}, journal = {IEEE transactions on visualization and computer graphics}, number = {1}, publisher = {IEEE}, address = {New York, NY}, issn = {1941-0506}, doi = {10.1109/TVCG.2015.2467717}, pages = {629 -- 638}, abstract = {We introduce a set of integrated interaction techniques to interpret and interrogate dimensionality-reduced data. Projection techniques generally aim to make a high-dimensional information space visible in form of a planar layout. However, the meaning of the resulting data projections can be hard to grasp. It is seldom clear why elements are placed far apart or close together and the inevitable approximation errors of any projection technique are not exposed to the viewer. Previous research on dimensionality reduction focuses on the efficient generation of data projections, interactive customisation of the model, and comparison of different projection techniques. There has been only little research on how the visualization resulting from data projection is interacted with. We contribute the concept of probing as an integrated approach to interpreting the meaning and quality of visualizations and propose a set of interactive methods to examine dimensionality-reduced data as well as the projection itself. The methods let viewers see approximation errors, question the positioning of elements, compare them to each other, and visualize the influence of data dimensions on the projection space. We created a web-based system implementing these methods, and report on findings from an evaluation with data analysts using the prototype to examine multidimensional datasets.}, subject = {Informationswissenschaft}, language = {en} } @misc{AlbrechtMuellerDoerk, author = {Albrecht, Kim and M{\"u}ller, Boris and D{\"o}rk, Marian}, title = {Culturegraphy - Visualizing Cultural Network Dynamics}, abstract = {Culturegraphy visualizes cultural information exchange over time.

The focus of visualization research has traditionally been on techniques, and to a lesser degree on the process of creating them with domain experts and end users. This paper focuses on the collaborative design of visualizations for information seeking and knowledge management. The difficult, yet common challenge in any visualization project is to find meaningful visual representations and useful interaction techniques to carry out complex analysis tasks. The unique difficulty for preparing co-design activities for visualization lies in the gap between the abstract nature of data and the concrete form of visual representations. To bridge this gap, our co-design framework for visualization places particular emphasis on actors, activities, and artifacts as categories that expand the focus of visualization design beyond the traditional triad of users, tasks, and data. Drawing from general co-design principles, the framework is developed and validated during the course of two case studies in the context of information management systems and library collection databases. Based on observed patterns during the case studies, practical tactics provide advice on carrying out co-design in information visualization.}, subject = {Methodologie}, language = {en} } @article{CorneliaKrieglerCarlsenetal., author = {Cornelia, Auer and Kriegler, Elmar and Carlsen, Henrik and Kok, Kasper and Pedde, Simona and Krey, Volker and M{\"u}ller, Boris}, title = {Climate change scenario services}, series = {One Earth}, volume = {4}, journal = {One Earth}, number = {8}, publisher = {Elsevier}, address = {Amsterdam}, issn = {2590-3322}, doi = {10.1016/j.oneear.2021.07.015}, pages = {1074 -- 1082}, abstract = {The goal of limiting global warming to well below 2°C as set out in the Paris Agreement calls for a strategic assessment of societal pathways and policy strategies. Besides policy makers, new powerful actors from the private sector, including finance, have stepped up to engage in forward-looking assessments of a Paris-compliant and climate-resilient future. Climate change scenarios have addressed this demand by providing scientific insights on the possible pathways ahead to limit warming in line with the Paris climate goal. Despite the increased interest, the potential of climate change scenarios has not been fully unleashed, mostly due to a lack of an intermediary service that provides guidance and access to climate change scenarios. This perspective presents the concept of a climate change scenario service, its components, and a prototypical implementation to overcome this shortcoming aiming to make scenarios accessible to a broader audience of societal actors and decision makers.}, subject = {Klima{\"a}nderung}, language = {en} } @inproceedings{OttenHildebrandNageletal., author = {Otten, Heike and Hildebrand, Lennart and Nagel, Till and D{\"o}rk, Marian and M{\"u}ller, Boris}, title = {Shifted Maps}, series = {2018 IEEE VIS Arts Program}, booktitle = {2018 IEEE VIS Arts Program}, publisher = {Institute of Electrical and Electronics Engineers (IEEE)}, address = {Berlin}, organization = {Institute of Electrical and Electronics Engineers (IEEE)}, isbn = {978-1-7281-2805-4}, doi = {10.1109/VISAP45312.2018.9046054}, pages = {1 -- 10}, abstract = {We present a hybrid visualization technique that integrates maps into network visualizations to reveal and analyze diverse topologies in geospatial movement data. With the rise of GPS tracking in various contexts such as smartphones and vehicles there has been a drastic increase in geospatial data being collect for personal reflection and organizational optimization. The generated movement datasets contain both geographical and temporal information, from which rich relational information can be derived. Common map visualizations perform especially well in revealing basic spatial patterns, but pay less attention to more nuanced relational properties. In contrast, network visualizations represent the specific topological structure of a dataset through the visual connections of nodes and their positioning. So far there has been relatively little research on combining these two approaches. Shifted Maps aims to bring maps and network visualizations together as equals. The visualization of places shown as circular map extracts and movements between places shown as edges, can be analyzed in different network arrangements, which reveal spatial and temporal topologies of movement data.
