The age of information means too much information. Users want relief from information overload. They need the ability to navigate and explore large data sets without getting buried. The challenge for application developers is to provide both an overview of huge data sets and a useful interface for drilling down to access details of interest. The use of new techniques for graphical visualisation of large hierarchies of information provides a solution to these problems. These new techniques apply knowledge gained from cognitive psychology and put them into practice. All to improve usability and lucidity for the user. In this thesis a case study has been conducted in order to provide proof to the above statement. An application was developed using the Visual tree studio from inxight. The application explored the Hyperbolic tree. The case study was connected to the theoretical part of the thesis and the conclusion is that using the hyperbolic tree when visualising large hierarchies of information will improve lucidity and usability.
