Enhanced Attribute-Based Explanations of Multidimensional Projections
(The Eurographics Association, 2020)
Multidimensional projections (MPs) are established tools for exploring the structure of high-dimensional datasets to reveal groups of similar observations. For optimal usage, MPs can be augmented with mechanisms that explain ...
Feature Driven Combination of Animated Vector Field Visualizations
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Animated visualizations are one of the methods for finding and understanding complex structures of time-dependent vector fields. Many visualization designs can be used to this end, such as streamlines, vector glyphs, and ...
Quantitative Comparison of Time-Dependent Treemaps
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Rectangular treemaps are often the method of choice to visualize large hierarchical datasets. Nowadays such datasets are available over time, hence there is a need for (a) treemaps that can handle time-dependent data, and ...
Visual Exploration of Neural Network Projection Stability
(The Eurographics Association, 2022)
We present a method to visually assess the stability of deep learned projections. For this, we perturb the high-dimensional data by controlled sequences and visualize the resulting changes in the 2D projection. We apply ...
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 ...
Identifying Cluttering Edges in Near-Planar Graphs
(The Eurographics Association, 2023)
Planar drawings of graphs tend to be favored over non-planar drawings. Testing planarity and creating a planar layout of a planar graph can be done in linear time. However, creating readable drawings of nearly planar graphs ...
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 ...
