Note
Graph layout features are only available if
you have purchased a full JViews Diagrammer license.
The SDM engine and renderers create the nodes and links in the
grapher, but the positions of these objects may not be ideal: some
nodes may overlap and there may be too many link
crossings, so that the resulting diagram can be difficult to
apprehend.
When a graph layout renderer is declared, a
graph layout algorithm positions the nodes and labels that are
stored in the grapher and routes the links.
There are several algorithms: some just
position nodes, others just route links, and some do both.
You need to choose from the various
algorithms available, and your choice will depend on the topology
of your diagram, and possibly on your industry. The many parameters
will help you to tune the algorithm to fit your specific needs. You
can use the Designer to help find the best solution.
