A method for pre-segmenting a large tree or treetable for purposes of visualization and deeper exploration of individual nodes, with the segments sized so as to allow inclusion of at least some amount of content-indicative text for each node. This invention pre-partitions a tree or treetable into segments of related nodes whose approximate maximum dimension permits significant text to be presented for each node. The segments can be visually differentiated in an outline depiction of the tree or treetable as a whole, and individual segments then extracted for deeper exploration. The segments may also be constrained to represent only nodes within the same logical grouping, which may be an identified subtopic, or collection of less-focused material, or other type of grouping. When the segments are so constrained, regions of adjacent segments associated with each such grouping can also be visually differentiated from other such regions.
