Rectangular treemaps divide a rectangle and then its subdivisions in a two-dimensional space, and have high space utilization in visualizing large hierarchical datasets. Most current treemaps, however, do not clearly show the relations between the items of the same level. This paper presents a new layout called concentric rings ordered tree (CROT), which hardly wastes any space and also shows sibling...
Visualizing and exploring a hierarchical structure on a smartphone screen is challenging. On larger screens of PCs and laptops these types of structures are often shown in a tabular view. Due to the width restriction, tabular view is not feasible on smaller screens. This paper presents a visualization technique that displays multiple levels of a hierarchical structure on a single view for small screens...
The adaptability of Web interfaces in response to changes in the interaction context, display environments (e.g., mobile screens) and user's personal preferences is becoming increasingly desirable due to the pervasive use of Web information. One of the major challenges in Web interface adaptation is to discover the semantic structure underlying a Web interface. This paper presents a robust and formal...
Visualization techniques have been widely used in representing software artifacts. They play a central role in conveying program information to software developers. While numerous tools have been developed to visualize information such as static software architectures, dynamic program behaviors, and debugging processes, little attention has been paid to visualizing correlations and variations among...
This paper presents a grammar-induction based approach to partitioning a Web page into several small pages while each small page fits not only spatially but also logically for mobile browsing. Our approach proceeds in three steps: (1) using the grammar induction technique to generate a graph grammar, which formalizes design policies for presenting information in a clear and logic structure; (2) based...
