International Exchange on Continuous Learning in Software Developement

Wed, 29 Apr 2026 09:55:00 +0200

We are co-organizing the Dagstuhl Seminar “Supporting Software Engineers in Lifelong Learning” later this year. Bringing together an international group of researchers, the seminar will explore how tools, data, and AI can better support continuous, on-the-job learning in software engineering. Dagstuhl Seminars are invitation-only and provide a focused setting for in-depth discussion and collaboration on emerging research challenges.

The Group has moved to a new location at KI25

Mon, 20 Apr 2026 11:59:11 +0200

Our research group has recently moved to a new location at Kirschäckerstraße 25 (KI25), close to FEKI, where a new site with a media focus is being established. So far, our group and Sophie Jörg’s Computer Graphics Lab have moved to the new location. Most teaching activities remain unaffected and continue to take place at Erba.

Visualization Pipeline Performance

Fri, 13 Feb 2026 08:49:00 +0100

Visualization pipelines are commonly represented as directed graphs, but analyzing and comparing their runtime performance remains challenging. In this work, we extend pipeline representations with fine-grained runtime metrics, enabling detailed post-mortem analysis and direct visual comparison of different pipeline configurations.

By integrating performance data directly into the visual structure, our approach helps identify bottlenecks, understand the impact of pipeline changes, and support more informed optimization decisions. We demonstrate the usefulness of the approach across multiple scientific visualization scenarios.

Interactive Data Widgets

Tue, 04 Nov 2025 08:53:26 +0100

Instead of only viewing data, users can select, modify, and create data directly within visualizations. Imagine drawing a crescent-shaped selection on a scatterplot, sketching a target time-series pattern, or adding points directly in the plot. viaWidgets turn visualizations into modular tools that feed structured input back into data workflows, particularly useful in notebook environments.

This idea builds on prior research and modern notebook widget ecosystems, showing how richer interaction can bridge visual exploration and coding.

PUREsuggest: Citation-based Visual Recommendatios of Literature

Wed, 13 Nov 2024 09:01:08 +0100

Abstract: Citations allow quickly identifying related research. If multiple publications are selected as seeds, specifc suggestions for related literature can be made based on the number of incoming and outgoing citation links to this selection. Interactively adding recommended publications to the selection refnes the next suggestion and incrementally builds a relevant collection of publications. Following this approach, the paper presents a search and foraging approach, PUREsuggest, which combines citation-based suggestions with augmented visualizations of the citation network. The focus and novelty of the approach is, frst, the transparency of how the rankings are explained visually and, second, that the process can be steered through user-defned keywords, which refect topics of interests. The system can be used to build new literature collections, to update and assess existing ones, as well as to use the collected literature for identifying relevant experts in the feld. We evaluated the recommendation approach through simulated sessions and performed a user study investigating search strategies and usage patterns supported by the interface.

Local Climate Data Stories

Fri, 18 Oct 2024 11:02:36 +0200

Our research group has contributed a new workshop article titled “Local Climate Data Stories: Data-driven Storytelling to Communicate Effects and Mitigation of Climate Change in a Local Context.” The work focuses on utilizing data-driven storytelling to communicate the local impacts of climate change, emphasizing the need for location-specific solutions. The study analyzes the use of this pproach by local news media, explores educational aspects through university teaching examples, and highlights interdisciplinary research opportunities.

"Not just alluvial" for Better Visual Comparison Among Set Partitions

Wed, 11 Sep 2024 18:10:00 +0200

At the conference "Vision, Modelling and Visualization (VMV) 2024", we presented our paper titled "Not Just Alluvial: Towards a More Comprehensive Visual Analysis of Data Partition Sequences", authored by Madhav Poddar, Jan-Tobias Sohns, and Fabian Beck. It extends the stream-based alluvial diagrams for better visual comparison among partitions of sets.

This paper contributes to Project CoCo by enabling the analysis of clustering result sequences. However, it is domain-agnostic, making it applicable to broader set of use cases, such as evaluating multi-label classifier models.

Our Research at EuroVis 2024

Short Paper Presentation: Dynamic Set Visualization

Our short paper focuses on dynamic set visualization. This empirical study compares three state-of-the-art set visualization approaches through a user study. The insights gained will help improve the understanding and effectiveness of these visualizations. [Paper]

Poster Presentations:

Data-Driven Storytelling with Public Transport Data: We present an approach to data-driven storytelling in virtual reality, using public transport data to communicate travel times within the local bus network to a broad audience. This method aims to enhance the accessibility and understanding of transport data, and includes plans for audio narration. [Paper]
Part-to-Whole Visualizations: This poster explores the design space of part-to-whole visualizations, discussing various aspects of visual encoding. Our goal is to contribute to the development of effective visualization techniques for representing part-to-whole relationships. [Paper]

We look forward to engaging with the community and sharing our findings at EuroVis 2024.

Personalized Hotel Comparisons

Tue, 23 Apr 2024 11:45:51 +0200

The proposed visual interface, ViSCitR, enhances the process of choosing hotels by integrating multiple comparison dimensions such as geographical location, category-specific ratings, rating trends, and summarized review points into an interactive document. The approach also includes a customizable sidebar allowing users to adjust their personal preferences and priorities, which dynamically alters the visual presentation.

While this work constitutes our final contribution to the vgiReports project (part of the VGIscience priority program funded by DFG), we are happy to continue our research toward more localized geographic data stories within the Smart City Bamberg initiative.
