CSE assistant professor Hongfeng Yu will speak next Tuesday, Sept. 5. His talk, "Edge Bundling Techniques towards Scalable Visualization of Large Graphs," will begin at 4 p.m. in Avery 115.
Abstract:
Graphs, also called networks, are widely used to model relationships between data entities in diverse scientific and engineering applications, such as systems biology, software engineering, social science, and so on. Directly visualizing a large graph as a node-link diagram often incurs visual clutter. Edge bundling can effectively address this issue and concisely reveal the main graph structure with reduced visual clutter. Although researchers have devoted noticeable efforts to develop acceleration methods, it remains a challenging task to efficiently conduct edge bundling, particularly, on devices with limited computing capacity, such as ubiquitous smart mobile devices. In this talk I will briefly revisit existing edge bundling work, and introduce a few techniques developed in our recent work leading to performance optimization of edge bundling. I will also demonstrate a few applications enabled by these techniques and discuss possible future directions.
