LineageD: An Interactive Visual System for Plant Cell Lineage Assignments based on Correctable Machine Learning
(The Eurographics Association and John Wiley & Sons Ltd., 2022)We describe LineageD-a hybrid web-based system to predict, visualize, and interactively adjust plant embryo cell lineages. Currently, plant biologists explore the development of an embryo and its hierarchical cell lineage ... -
HyperNP: Interactive Visual Exploration of Multidimensional Projection Hyperparameters
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Projection algorithms such as t-SNE or UMAP are useful for the visualization of high dimensional data, but depend on hyperparameters which must be tuned carefully. Unfortunately, iteratively recomputing projections to find ... -
Exploring Effects of Ecological Visual Analytics Interfaces on Experts' and Novices' Decision-Making Processes: A Case Study in Air Traffic Control
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Operational demands in safety-critical systems impose a risk of failure to the operators especially during urgent situations. Operators of safety-critical systems learn to make decisions effectively throughout extensive ... -
A Flip-book of Knot Diagrams for Visualizing Surfaces in 4-Space
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Just as 2D shadows of 3D curves lose structure where lines cross, 3D graphics projections of smooth 4D topological surfaces are interrupted where one surface intersects itself. They twist, turn, and fold back on themselves, ... -
Six Methods for Transforming Layered Hypergraphs to Apply Layered Graph Layout Algorithms
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Hypergraphs are a generalization of graphs in which edges (hyperedges) can connect more than two vertices-as opposed to ordinary graphs where edges involve only two vertices. Hypergraphs are a fairly common data structure ... -
LOOPS: LOcally Optimized Polygon Simplification
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Displaying polygonal vector data is essential in various application scenarios such as geometry visualization, vector graphics rendering, CAD drawing and in particular geographic, or cartographic visualization. Dealing ... -
Branch Decomposition-Independent Edit Distances for Merge Trees
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Edit distances between merge trees of scalar fields have many applications in scientific visualization, such as ensemble analysis, feature tracking or symmetry detection. In this paper, we propose branch mappings, a novel ... -
Interactively Assessing Disentanglement in GANs
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Generative adversarial networks (GAN) have witnessed tremendous growth in recent years, demonstrating wide applicability in many domains. However, GANs remain notoriously difficult for people to interpret, particularly for ... -
SurfNet: Learning Surface Representations via Graph Convolutional Network
(The Eurographics Association and John Wiley & Sons Ltd., 2022)For scientific visualization applications, understanding the structure of a single surface (e.g., stream surface, isosurface) and selecting representative surfaces play a crucial role. In response, we propose SurfNet, a ... -
EuroVis 2022 CGF 41-3: Frontmatter
(The Eurographics Association and John Wiley & Sons Ltd., 2022) -
An Interactive Approach for Identifying Structure Definitions
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Our ability to grasp and understand complex phenomena is essentially based on recognizing structures and relating these to each other. For example, any meteorological description of a weather condition and explanation of ... -
A Typology of Guidance Tasks in Mixed-Initiative Visual Analytics Environments
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Guidance has been proposed as a conceptual framework to understand how mixed-initiative visual analytics approaches can actively support users as they solve analytical tasks. While user tasks received a fair share of ... -
ModelWise: Interactive Model Comparison for Model Diagnosis, Improvement and Selection
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Model comparison is an important process to facilitate model diagnosis, improvement, and selection when multiple models are developed for a classification task. It involves careful comparison concerning model performance ... -
Leveraging Analysis History for Improved In Situ Visualization Recommendation
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Existing visualization recommendation systems commonly rely on a single snapshot of a dataset to suggest visualizations to users. However, exploratory data analysis involves a series of related interactions with a dataset ... -
Seeing Through Sounds: Mapping Auditory Dimensions to Data and Charts for People with Visual Impairments
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Sonification can be an effective medium for people with visual impairments to understand data in visualizations. However, there are no universal design principles that apply to various charts that encode different data ... -
A Process Model for Dashboard Onboarding
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Dashboards are used ubiquitously to gain and present insights into data by means of interactive visualizations. To bridge the gap between non-expert dashboard users and potentially complex datasets and/or visualizations, ... -
A Grammar-Based Approach for Applying Visualization Taxonomies to Interaction Logs
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Researchers collect large amounts of user interaction data with the goal of mapping user's workflows and behaviors to their high-level motivations, intuitions, and goals. Although the visual analytics community has proposed ... -
Of Course it's Political! A Critical Inquiry into Underemphasized Dimensions in Civic Text Visualization
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Recent developments in critical information visualization have brought the field's attention to political, feminist, ethical, and rhetorical aspects of data visualization. However, less work has explored the interplay ... -
LMFingerprints: Visual Explanations of Language Model Embedding Spaces through Layerwise Contextualization Scores
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Language models, such as BERT, construct multiple, contextualized embeddings for each word occurrence in a corpus. Understanding how the contextualization propagates through the model's layers is crucial for deciding which ... -
Infographics Wizard: Flexible Infographics Authoring and Design Exploration
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Infographics are an aesthetic visual representation of information following specific design principles of human perception. Designing infographics can be a tedious process for non-experts and time-consuming, even for ...
