Abstract
We present a novel tree browser that builds on the conventional node link tree
diagrams. It adds dynamic rescaling of branches of the tree to best fit the
available screen space, optimized camera movement, and the use of preview icons
summarizing the topology of the branches that cannot be expanded. In addition,
it includes integrated search and filter functions. This paper reflects on the
evolution of the design and highlights the principles that emerged from it. A controlled experiment showed benefits for navigation to already previously
visited nodes and estimation of overall tree topology.
