Read the project description carefully. Questions and comments can be sent to

General information

The purpose of the project work is to get hands on experience and deeper understanding on one specific area of the course. At the same time you will be forced to think on some of the more general issues that are confronted every time a visualization method is developed or used.

To complete the project you will probably need information that has not been discussed on the lectures or in the exercises. Most of the time relevant information can be easily found on the web, course books or in some cases references to articles will be given. If you have problems finding information on the subject please contact the lecturer or the assistant for hints and guidance.

The project work will be valid for one year after the original deadline.

General requirements

specific requirements

The goal of this project is to create a tool to visualize a tree structure using a tree map (See. Card et al).

The tool should have the following features

  1. It should read the tree from a file (or possibly from stdin). The file format could be for example the on generated by the Unix tree command.

  2. The user should be able to manipulate the map, e.g. zoom in and out etc.
