Optimizing Stepwise Animation in Dynamic Set Diagrams
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
A set diagram represents the membership relation among data elements. It is often visualized as secondary information on top of primary information, such as the spatial positions of elements on maps and charts. Visualizing ...
A Random Sampling O(n) Force-calculation Algorithm for Graph Layouts
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
This paper proposes a linear-time repulsive-force-calculation algorithm with sub-linear auxiliary space requirements, achieving an asymptotic improvement over the Barnes-Hut and Fast Multipole Method force-calculation ...
A Stable Graph Layout Algorithm for Processes
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Process mining enables organizations to analyze data about their (business) processes. Visualization is key to gaining insight into these processes and the associated data. Process visualization requires a high-quality ...
Route-Aware Edge Bundling for Visualizing Origin-Destination Trails in Urban Traffic
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Origin-destination (OD) trails describe movements across space. Typical visualizations thereof use either straight lines or plot the actual trajectories. To reduce clutter inherent to visualizing large OD datasets, bundling ...
