Hierarchical display

display of a thesaurus structure based on broader/narrower concept relationships

In such a display narrower terms are commonly shown indented under the broader term which is their parent. Each hierarchy, starting from a "top term" contains terms from only a single facet or subfacet, so node labels containing facet names do not occur within hierachies, though they may be shown at the top of each. A hierarchical display may contain node labels specifying characteristics of division. An example of a hierarchical display is shown under characteristic of division.
