Dear Academic friends, We’re pleased to announce the call for papers for the Input Visualization Workshop, co-located with the IEEE VIS Conference in Vienna, Austria, taking place from November 2 to 7. Input visualization — “visual representations that are designed to collect (and represent) new data rather than encode pre-existing datasets” — provides a new lens for direct interactions with data through visualizations and physicalizations. You can find a collection of input visualization online here: https://inputvisualization.github.io/ For the workshop, we invite three types of submissions for the workshop: (1) Position papers, (2) Examples of input visualizations, (3) Expressions of interest to participate in the workshop without submitting a paper or example to help us estimate the number of attendees. 👉: https://forms.gle/T6wmARWrcZfMRwS28 🫶🏻 (1) Position papers: We invite 2+ page position papers or pictorials that identify, highlight, or address key challenges related to interaction and input in visualizations, including (but not limited to): - New or existing input visualization designs. - New or overlooked use cases for interaction in visualizations. - Case studies of participatory visualization and physicalization in practice. - New interaction techniques for inputting, modifying, or annotating data via visual interfaces. - Novel physical, tangible, or tool-driven approaches to interacting with visualizations. - Design principles, challenges, or opportunities for interactive visualizations. Submissions should use the VGTC conference two-column format or DIS Pictorial format. Submissions will be shared with participants before the workshop. At least one author of each accepted paper must attend the workshop and must register for at least one day of the conference. For more details, please visit the workshop's website at: https://inputvisualization.github.io/vis2025/. Submission deadline: August 4, 2025 Notification: August 19, 2025 🫶🏻 (2) Examples of input visualizations: Alternatively, we also invite submissions of examples of input visualizations that you find inspiring or relevant, whether from your own research or other sources. We will use these examples during the workshop as we aim to expand our evolving corpus of input visualizations. Please include an image and a short description of the example, as well as an explanation of why you find this example interesting or inspiring. Submissions should be provided in PDF format, or any other format that fits your submission. 🫶🏻 (3) Expressions of interest to participate: If you are interested in participating in the workshop, even without submitting a position paper or example, please fill out the form as well, as this will help us estimate the number of attendees. Best Regards, Workshop Organizers Nathalie Bressa, Samuel Huron, Wesley Willett, Evanthia Dimara, Kim Sauvé, Derya Akbaba

Graph Drawing and Network Visualization are motivated by applications for which it is crucial to visually analyze and interact with relational datasets. Application areas include data science, social sciences, web computing, information systems, life sciences, geography, business intelligence, information security, and software engineering. Graph Drawing has been the main annual conference in this area for more than 30 years. Its focus is on combinatorial and algorithmic aspects of graph drawing, their experimental evaluation, as well as the design of network visualization systems and interfaces. Researchers and practitioners working on any aspects of graph drawing and network visualization are invited to contribute papers and posters and to participate in the symposium as well as the graph drawing contest. GD 2025 will be held in Norrköping, Sweden, on September 24-26, 2025 with a reception on the evening of September 23. A preconference PhD school will take place September 22-23, 2025. GD 2025 is designed to be held on-site. It is expected that regular papers are presented on site by one of the authors. To address the global challenges and as an offer for authors who are unable to attend we allow for a limited number of remote presentations, as further explained below. The code of conduct for the GD conference can be found at http://graphdrawing.org/safetoc.html ================================================================ *POSTERS* Submissions of posters on graph drawing, network visualization, and related areas are solicited. The poster session will provide a forum for the communication of late-breaking research results (which may also appear elsewhere) to the GD community. Authors of posters should prepare an abstract that must be submitted together with the poster itself. Each submission will thus consist of two pdf files (the abstract and the poster). ================================================================ RULES FOR SUBMISSION Each poster must be presented at the conference by an author. The proceedings will be published in the LIPIcs <https://www.dagstuhl.de/en/publishing/series/details/lipics> series. To facilitate the process, submissions have to be prepared in accordance with the LIPIcs author instructions <https://submission.dagstuhl.de/series/details/LIPIcs#author>, the page provides links to the LIPIcs class file along with an example and detailed author instructions. For the submission, the use of the LaTeX class file gd-lipics-v2.cls <https://graphdrawing.github.io/gd2025/assets/template/gd-lipics-v2.cls> is requested. The class file is a wrapper around the standard LIPIcs class and implements line counting, see CG-linecount.pdf <https://www.computational-geometry.org/guidelines/linecount_2022_09_19.pdf> for details. Submissions must not exceed the following limits: - 80 lines for posters’ abstracts. The above limits do not include front matter (title, authors, and affiliations) and references. The class files provide line counting which should be accurate in most cases. Authors should avoid substantial amounts of text in unnumbered lines. In addition, the main content of the paper must not exceed the following page limits excluding references: - 3 pages for posters’ abstracts. For poster submissions, no appendix is expected. We also encourage authors to avoid "et al." in citations in favor of an equal mention of the surnames of all authors. For references with few authors, it is recommended to name all of them; if the number of authors is large, consider writing "(It is shown that) X [#]" or "The authors in [#] show that X" instead of "A et al. [#] show that X". Posters should be submitted electronically via Easychair <https://easychair.org/conferences/?conf=gd2025>. The proceedings will be published in the *Leibniz International Proceedings in Informatics (LIPIcs)* series and are available open access. ================================================================ SINGLE-BLIND REVIEW PROCESS Poster submissions will be evaluated by the Program Committee in a single-blind mode. In particular, the submitted abstract should contain the authors’ names, affiliations, and email addresses. ================================================================ AWARDS To recognize the effort of participants to prepare their posters in a clear and elegant way, there will be a Best Poster Award voted on by the GD 2025 attendees. ================================================================ INVITED SPEAKERS Hans Bodlaender, Utrecht University, Netherlands Huamin Qu, Hong Kong University of Science and Technology (HKUST), Hong Kong ================================================================ ORGANIZING COMMITTEE Andreas Kerren, Linköping University, Sweden (general co-chair) Kostiantyn Kucher, Linköping University, Sweden (general co-chair) Claudio Linhares, Linnaeus University, Sweden (PhD school chair) Nico Reski, Linköping University, Sweden (Decision Arena chair) Zeyang Huang, Linköping University, Sweden (web chair) ================================================================ PROGRAM COMMITTEE Alessio Arleo, TU Eindhoven, Netherlands Michael Bekos, University of Ioannina, Greece Markus Chimani, University of Osnabrück, Germany Éric Colin de Verdière, CNRS, LIGM, Marne-la-Vallée, France Giordano Da Lozzo, Roma Tre University, Italy Sara Di Bartolomeo, TU Wien, Austria Vida Dujmovic, University of Ottawa, Canada (program co-chair) Henry Förster, TU Munich, Germany Fabrizio Frati, Roma Tre University, Italy Robert Ganian, TU Wien, Austria Daniel Gonçalves, CNRS & University of Montpellier, France Siddharth Gupta, BITS Pilani, K K Birla Goa Campus, India Thekla Hamm, TU Eindhoven, Netherlands Takayuki Itoh, Ochanomizu University, Japan Philipp Kindermann, Trier University, Germany Stephen Kobourov, TU Munich, Germany Kostiantyn Kucher, Linköping University, Sweden Silvia Miksch, TU Wien, Austria Fabrizio Montecchiani, University of Perugia, Italy (program co-chair) Pat Morin, Carleton University, Canada Tamara Mchedlidze, Utrecht University, Netherlands Giacomo Ortali, University of Perugia, Italy Sergey Pupyrev, Meta, USA Marcus Schaefer, DePaul University, USA Raphael Steiner, ETH Zurich, Switzerland Andrew Suk, University of California San Diego, USA Antonios Symvonis, National Technical University of Athens, Greece Csaba D.
