VisGap - The Gap between Visualization Research and Visualization Software

Monday, June 12, 2023 · 2pm to 6pm, CEST · Leipzig, Germany
Held in conjunction with EuroVis 2023.


Registration is open. Early-bird deadline: April 26, 2022.
Organized by Christina Gillmann, Michael Krone, Guido Reina, and Thomas Wischgoll.


Over the years, many visualization methods and tools have been developed and published by the visualization research community. However, most of these are prototypes and never reach a state that can be reliably used by the target audience, e.g., domain scientists. Also, availability of these prototypes as source code or at least as executables is still the exception rather than the norm. The VisGap Symposium aims to shed a light on this gap between research and practical applicability, examine the obstacles every researcher faces, and propose solutions to overcome this problem as a community.

VisGap aims at gathering experts from all over the visualization community in order to advance the way our field works with software, sustains software, and values the effort our members put into developing said software. The scope of VisGap also includes reproducibility and replicability. Both are cornerstones of the scientific method and essential for building trust in visualizations and increasing their acceptance, ultimately fostering adoption in the wild.


Topics include, but are not limited to:

  • Requirements for successful visualization in applications in general
  • Domain-specific requirements for visualizations
  • Reflections on the research community and the visualization software ecosystem
  • Incentives and funding for developing/maintaining visualization research software
  • Legal requirements (e.g., licensing, certification) for visualizations in applications
  • Case studies of (un)successful visualization solutions in applications
  • Requirements for novel visualization libraries
  • Verification and validation in visualization (applications)
  • Reproducibility of visualization

Keynote: Approaches for the successful delivery of open-source visualization software
Session Chair: Christina Gillmann

In this talk, I will describe approaches to successful creation of open-source visualization software. In summary, these approaches include defining and following clear project objectives and community policies, the use of agile software engineering methods, and the use of continuous integration and deployment practices. I believe these approaches are scalable from small to large teams. These approaches were developed and refined over the course of my career. During my career, I have researched, developed, and deployed open-source software tools including ParaView, a large-scale scientific visualization tool, Cinema, an image database approach for visual analysis, PISTON, a portable data parallel visualization library, ALPINE, in situ visualization infrastructure and algorithms, and, DSI, a data science infrastructure project. Real-world successes and failures during the development of these approaches and tools will be discussed. In addition, specific challenges of facing researchers and developers of visualization software, such as user interface development, user testing, use of graphics software and hardware libraries, and performance and portability concerns will also be discussed.

Software prototypes developed as part of research projects are often a rich source of novel innovative approaches to solving real-world problems. Yet there are few examples where such prototypes have evolved into mature and sustainable software or even products. The challenges involved are manifold - from the right composition of the team to the selection and maintenance of the technology to sustainable funding over many years, just to name a few.

VRVis is an Austrian research center for visual computing with the mission to bring scientific research results into application. Since its founding in 2000, several software frameworks have emerged that today form a foundation for basic research at VRVis, but are also the subject of large-scale applied research projects supported by industry, government, and academia. Many of these frameworks have evolved from initial research ideas and prototypes into a large software base that is actively used and subject to constant evolution and change. I will present a selection of these frameworks and provide practical insights into the history and strategies of the various teams behind the software creating a sustainable product. Showing that there is not a single and straight path to success, but many, I invite you to take this as an inspiration for finding your way to develop your own software towards a sustainable framework.

5:25 PM – 5:30 PM


We solicit papers with 4-8 pages in the VisGap 2023 latex style (see above for the scope of the workshop), with an additional page allowed for references. All submissions must be original works that have not been published previously in any conference proceedings, magazine, journal, or edited book or must present a substantial extension of previous work (at least 30%). Papers are to be submitted via PCS. Please find the LaTeX template here

All submissions will undergo a single-blind, single-stage peer review process. Accepted papers will be published by the Eurographics Association, and be stored in the Eurographics Digital Library. At least one author of each accepted paper must register and participate in the VisGap 2023 workshop to present the accepted work.

All papers must be submitted through PCS ( (Society: Eurographics; Conference/Journal: VisGap 2023)


Jan 27, 2023 :  Early submission notification of acceptance
Apr 24, 2023 :  Regular submission notification of acceptance
Jun 12, 2023 :  Workshop
