Structure of Organisations
One possible application of the applet is to visualise the structure of large organisations. For example, the following graph shows the structure of the University of Bochum in Germany. Some of the nodes are links to the corresponding homepage, for example the green nodes for the faculties in natural sciences and the red "Faculty of Medicine". Clicking on these nodes will open the homepage in a new window.
You see in this graph that one should keep the labels small and precise - I havent't done this here and especially the names of the different hospitals are simply to long to be shown nicely. But I think, nobody would expect a label like "Abteilung fuer Psychosomatik und Psychotherapeutische Medizin, Universitaetsklinik am Westf. Zentrum fuer Psychiatrie, Psychotherapie und Psychosomatik Dortmund" to be shown well.
