General information about the FL

FL samples

These samples show the use of the Force-directed layout (class ForceDirectedLayout from the package ibm_ilog.graphlayout.forcedirected).
The following sample drawings are produced with the Force-directed Layout (FL).

What types of graphs suit the FL?

Any type of graph:
  • connected graphs and disconnected graphs
  • planar graphs and nonplanar graphs

Application domains for FL

Application domains for Force-directed include:
  • Telecoms and networking (WAN diagrams)
  • Software management/software (re-)engineering (call graphs)
  • CASE tools (dependency diagrams)
  • Database and knowledge engineering (such as semantic networks, database query graphs, qualitative reasoning, and other artificial intelligence diagrams)
  • World Wide Web (Web hyperlink neighborhood)
