HL samples
Describes the Hierarchical
Layout algorithm (class HierarchicalLayout from the package ibm_ilog.graphlayout.hierarchical).
The following sample drawings are produced with the Hierarchical
Layout:

Sample layout with self-loops, multiple links, and
cycles

Flowchart with orthogonal link style

Sample layout with ports and orthogonal link style

Sample layout of nested graph in recursive layout
mode
What types of graphs suit the HL?
Any type of graph, as follows:
- preferably graphs with directed links
- connected graphs and disconnected graphs
- planar graphs and nonplanar graphs
- nested graphs with intergraph links
Application domains for the HL
Application domains for the Hierarchical Layout include:
- Electrical engineering (logic diagrams, circuit block diagrams)
- Industrial engineering (industrial process diagrams, schematic design diagrams)
- Business processing (workflow diagrams, process flow diagrams, PERT charts)
- Software management/software (re-)engineering (UML diagrams, flowcharts, data inspector diagrams, call graphs)
- Database and knowledge engineering (database query graphs)
- CASE tools (designs diagrams)
