Characterizing Creativity in Data Visualization: Reflections and Future Directions
Tianwei Ma, Zinat Ara, Safwat Ali Khan +3
Characterizing creativity in visualization design can lead to the design of more expressive representations and visualization authoring tools that prioritize human creativity. In t…
Squidgets: Sketch-based Widget Design for Scene Manipulation
Joonho Kim, Fanny Chevalier, Karan Singh
People naturally sketch strokes over graphical scenes to convey scene changes. We propose automatically interpreting these strokes to execute scene changes with squidgets (sketch-w…
Large Language Lovers: Lived Experiences of Negotiating Agency and Platform Control in AI Companionship
Patrick Yung Kang Lee, Jessica Y. Bo, Zixin Zhao +6
Individuals are turning to increasingly anthropomorphic, general-purpose chatbots for AI companionship, rather than roleplay-specific platforms. However, not much is known about ho…
Computational Skills by Stealth in Secondary School Data Science
Wesley Burr, Fanny Chevalier, Christopher Collins +3
The unprecedented growth in the availability of data of all types and qualities and the emergence of the field of data science has provided an impetus to finally realizing the impl…
Visual Story-Writing: Writing by Manipulating Visual Representations of Stories
Damien Masson, Zixin Zhao, Fanny Chevalier
We define "visual story-writing" as using visual representations of story elements to support writing and revising narrative texts. To demonstrate this approach, we developed a tex…
The Effect of Smoothing on the Interpretation of Time Series Data: A COVID-19 Case Study
Oded Stein, Alec Jacobson, Fanny Chevalier
We conduct a controlled crowd-sourced experiment of COVID-19 case data visualization to study if and how different plotting methods, time windows, and the nature of the data influe…
Textoshop: Interactions Inspired by Drawing Software to Facilitate Text Editing
Damien Masson, Young-Ho Kim, Fanny Chevalier
We explore how interactions inspired by drawing software can help edit text. Making an analogy between visual and text editing, we consider words as pixels, sentences as regions, a…
Designing Narrative-Focused Role-Playing Games for Visualization Literacy in Young Children
Elaine Huynh, Angela Nyhout, Patricia Ganea +1
Building on game design and education research, this paper introduces narrative-focused role-playing games as a way to promote visualization literacy in young children. Visualizati…
FaceValue: Exploring Real-Time Self-View Overlays to Prompt Meaning-Oriented Self-Awareness in Remote Meetings
Gun Woo Warren Park, Anthony Tang, Fanny Chevalier
In remote video meetings, visual non-verbal cues, such as facial expressions or head movements, are seen continuously but often only partially. This increases ambiguity compared to…
Making the Write Connections: Linking Writing Support Tools with Writer's Needs
Zixin Zhao, Damien Masson, Young-Ho Kim +2
This work sheds light on whether and how creative writers' needs are met by existing research and commercial writing support tools (WST). We conducted a need finding study to gain…
Texterial: A Text-as-Material Interaction Paradigm for LLM-Mediated Writing
Jocelyn Shen, Nicolai Marquardt, Hugo Romat +3
What if text could be sculpted and refined like clay -- or cultivated and pruned like a plant? Texterial reimagines text as a material that users can grow, sculpt, and transform. C…
The HaLLMark Effect: Supporting Provenance and Transparent Use of Large Language Models in Writing with Interactive Visualization
Md Naimul Hoque, Tasfia Mashiat, Bhavya Ghai +4
The use of Large Language Models (LLMs) for writing has sparked controversy both among readers and writers. On one hand, writers are concerned that LLMs will deprive them of agency…
Does This Have a Particular Meaning? Interactive Pattern Explanation for Network Visualizations
Xinhuan Shu, Alexis Pister, Junxiu Tang +2
This paper presents an interactive technique to explain visual patterns in network visualizations to analysts who do not understand these visualizations and who are learning to rea…
Reflections and Considerations on Running Creative Visualization Learning Activities
Jonathan C. Roberts, Benjamin Bach, Magdalena Boucher +11
This paper draws together nine strategies for creative visualization activities. Teaching visualization often involves running learning activities where students perform tasks that…
Designing Resource Allocation Tools to Promote Fair Allocation: Do Visualization and Information Framing Matter?
Arnav Verma, Luiz Morais, Pierre Dragicevic +1
Studies on human decision-making focused on humanitarian aid have found that cognitive biases can hinder the fair allocation of resources. However, few HCI and Information Visualiz…
Considerations for Visualizing Uncertainty in Clinical Machine Learning Models
Caitlin F. Harrigan, Gabriela Morgenshtern, Anna Goldenberg +1
Clinician-facing predictive models are increasingly present in the healthcare setting. Regardless of their success with respect to performance metrics, all models have uncertainty.…
A Coin Flip Per Token: Bernoulli Sparse Steering of Large Language Models
Nima Eshraghi, Lovedeep Gondara, Yuqing Huang +5
Activation steering via sparse autoencoders (SAEs) enables behavioral control of large language models without task-specific fine-tuning, but standard methods apply the steering si…
IEEE VIS Workshop on Visualization for Climate Action and Sustainability
Benjamin Bach, Fanny Chevalier, Helen-Nicole Kostis +3
This first workshop on visualization for climate action and sustainability aims to explore and consolidate the role of data visualization in accelerating action towards addressing…
Common Fate for Animated Transitions in Visualization
Amira Chalbi, Jacob Ritchie, Deokgun Park +4
The Law of Common Fate from Gestalt psychology states that visual objects moving with the same velocity along parallel trajectories will be perceived by a human observer as grouped…
