Standard treemaps often lead to thin rectangles. The Faculty of Mathemathics and Computer Science
of the Technische Universiteit Eindhoven in The Netherlands, have developed a new method to display
files: Squarified treemaps.
The screen is subdivided such that rectangles approach squares as closely as possible. The screenshot
gives an example.

Ever wondered why your hard disk is full? Or what directory is taking up most of the space? When using
conventional disk browsing tools, such as Windows Explorer, these questions may be hard to answer.
With SequoiaView however, they can be answered almost immediately. SequoiaView uses a visualization
technique called cushion treemaps to provide you with a single picture of the entire contents of your
hard drive. You can use it to locate those large files that you haven't accessed in one year, or to quickly
locate the largest picture files on your drive. The screenshots below give a first impression of the original cushion treemaps:

Locate those big files you never use

SequoiaView was developed by the computer science department of the Technische Universiteit Eindhoven
and can be downloaded for free from these pages. For more background information click the image at the
