SpaceTree: a novel node-link tree browser
SpaceTree is a novel tree browser that builds on the conventional layout node link diagrams along a single preferred direction. 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 tasks to already previously visited nodes and estimation of overall tree topology.
