ChatKG: Visualizing Temporal Patterns as Knowledge Graph
(The Eurographics Association, 2023)Line-chart visualizations of temporal data enable users to identify interesting patterns for the user to inquire about. Using oracles, such as chat AIs, Visual Analytic tools can automatically uncover explicit knowledge ... -
Extracting Movement-based Topics for Analysis of Space Use
(The Eurographics Association, 2023)We present a novel approach to analyze spatio-temporal movement patterns using topic modeling. Our approach represents trajectories as sequences of place visits and moves, applies topic modeling separately to each collection ... -
KidCAD: An Interactive Cohort Analysis Dashboard of Patients with Chronic Kidney Diseases
(The Eurographics Association, 2023)Chronic Kidney Diseases (CKD) are a prominent health problem. With an ongoing process, CKD leads to impaired kindey function with decreased ability to filter the patients' blood, concluding in multiple complications, like ... -
A Methodology for Task-Driven Guidance Design
(The Eurographics Association, 2023)Mixed-initiative Visual Analytics (VA) systems are becoming increasingly important; however, the design of such systems still needs to be formulated. We present a methodology to aid and structure the design of guidance for ... -
Multi-Ensemble Visual Analytics via Fuzzy Sets
(The Eurographics Association, 2023)Analysis of ensemble datasets, i.e., collections of complex elements such as geochemical maps, is widespread in science and industry. The elements' complexity arises from the data they capture, which are often multivariate ... -
Nonparametric Dimensionality Reduction Quality Assessment based on Sortedness of Unrestricted Neighborhood
(The Eurographics Association, 2023)High-dimensional data are known to be challenging to explore visually. Dimensionality Reduction (DR) techniques are good options for making high-dimensional data sets more interpretable and computationally tractable. An ... -
A Practical Approach to Provenance Capturing for Reproducible Visual Analytics at an Ocean Research Institute
(The Eurographics Association, 2023)Reproducibility - and the lack thereof - has been an important topic for some time in the field of Human-Computer Interaction. Visual analytics workflows and in extension immersive analytics workflows are no exception there ... -
Scaling Up the Explanation of Multidimensional Projections
(The Eurographics Association, 2023)We present a set of interactive visual analysis techniques aiming at explaining data patterns in multidimensional projections. Our novel techniques include a global value-based encoding that highlights point groups having ... -
ShaRP: Shape-Regularized Multidimensional Projections
(The Eurographics Association, 2023)Projections, or dimensionality reduction methods, are techniques of choice for the visual exploration of high-dimensional data. Many such techniques exist, each one of them having a distinct visual signature - i.e., a ... -
A Visual Analytics Framework for Renewable Energy Profiling and Resource Planning
(The Eurographics Association, 2023)Renewable energy growth is one of the focus areas globally against the backdrop of the global energy crisis and climate change. Energy planners are looking into clean, safe, affordable, and reliable energy generation sources ...
