collapseSubGraph method
void
collapseSubGraph()
Hide each of the member nodes and links of this group, and recursively collapse any member groups. This changes the value of Part#isVisible of the whole subgraph and the parts owned by those member nodes and links. However, this group's visibility is unchanged.
This sets #isSubGraphExpanded to false on this group and on all of the nested Groups. For those nested Groups that were expanded, #wasSubGraphExpanded is set to true.
This method does not perform a transaction or start any animation.
To collapse trees made of Nodes and Links, use Node#collapseTree.
