Treemap
In information visualization and computing, treemapping is a method for displaying hierarchical data using Nesting (computing), nested figures, usually rectangles. Treemaps display hierarchical (Tree (data structure), tree-structured) data as a set of nested rectangles. Each branch of the tree is given a rectangle, which is then tiled with smaller rectangles representing sub-branches. A leaf node's rectangle has an area proportional to a specified Dimension (metadata), dimension of the data. Often the leaf nodes are colored to show a separate dimension of the data. When the color and size dimensions are correlated in some way with the tree structure, one can often easily see patterns that would be difficult to spot in other ways, such as whether a certain color is particularly prevalent. A second advantage of treemaps is that, by construction, they make efficient use of space. As a result, they can legibly display thousands of items on the screen simultaneously. Tiling algorith ...

Ben Shneiderman
Ben Shneiderman (born August 21, 1947) is an American computer scientist, a Distinguished University Professor in the University of Maryland Department of Computer Science, which is part of the University of Maryland College of Computer, Mathematical, and Natural Sciences at the University of Maryland, College Park, and the founding director (1983-2000) of the University of Maryland Human-Computer Interaction Lab. He conducted fundamental research in the field of human–computer interaction, developing new ideas, methods, and tools such as the direct manipulation interface, and his eight rules of design. Early life and education Born in New York, Shneiderman, attended the Bronx High School of Science, and received a BS in Mathematics and Physics from the City College of New York in 1968. He then went on to study at the State University of New York at Stony Brook, where he received an MS in Computer Science in 1972 and graduated with a PhD in 1973. Career Shneiderman star ...

Jarke Van Wijk
Jarke J. (Jack) van Wijk (born 1959) is a Dutch computer scientist, a professor in the Department of Mathematics and Computer Science at the Eindhoven University of Technology, and an expert in information visualization. Biography Van Wijk received his M.S. from the Delft University of Technology in 1982. His master's thesis, on simulation of traffic collisions, led him to become interested in computer visualization, and he remained at Delft for his doctoral studies, completing a Ph.D. in 1986 under the supervision of Dennis J. McConalogue. He worked at the Energy Research Centre of the Netherlands from 1988 until 1998, when he joined the Eindhoven faculty; he was promoted to a full professorship in 2001. As well as being a faculty member at TU Eindhoven, van Wijk is the vice president for scientific affairs at MagnaView, a Dutch information visualization company.
