PT Unknown AU Rüegg, U Schulze, CD Grevismühl, D von Hanxleden, R TI Using One-Dimensional Compaction for Smaller Graph Drawings SE Bericht des Instituts für Informatik PY 1992 VL 1601 PU Institut für Informatik WP https://macau.uni-kiel.de/receive/macau_mods_00002009 LA en SN 2192-6247 AB We review the technique of one-dimensional compaction and use it as part of two new methods tackling problems in the context of automatic diagram layout: First, a postprocessing of the layer-based layout algorithm, also known as Sugiyama layout, and second a placement algorithm for connected components with external extensions. We apply our methods to dataflow diagrams from practical applications and find that the first method significantly reduces the width of left-to-right drawn diagrams. The second method allows to properly arrange disconnected graphs that have hierarchycrossing edges.
