After populating a graph pane with nodes, I hoped I could persist that pane, ie: persist which nodes are chosen and where they are positioned, a misunderstanding on my part. Now I see the value of graphcanvas's "links" If I _link_ the nodes I've chosen to live on the pane, _that_ relationship is persisted. Of course the GC links have more value than persistence, which will be revealed as I use them more.
