Colloquy Cycle 3.9.2019 10h "Visualizing Trees" Prof. Xiaoru Yuan (Peking University, China)
In this talk, I will introduce a few recent work on tree visualization.
First I will present a visualization technique for comparing topological structures and node attribute values of multiple trees. I will further introduce GoTree, a declarative grammar supporting the creation of a wide range of tree visualizations. In the application side, visualization and visual analytics on social media will be introduced. The data from social media can be considered as graphs or trees with complex attributes. A few approaches using map metaphor for social media data visualization will be discussed.
