I introduced the frames to delay the layout of the nodes until the end.

Before I introduced the frames, you needed to layout the nodes while you are building your visualization. However, it may happen that edges are added later on in a script.

Consider the example:

1 - view node: 'hello' forIt: [ 2 - view nodes: #(1 2). 3 - view treeLayout. 4 - ]. 5 - view edgeFromAssociation: 1 -> 2.

In Lines 2 and 3 you defines two nodes and layout them. But there is no edge defined yet. The edge between 1 and 2 is defined after you have set which layout you want to use. So the tree layout has to be delayed until the very hand.

The edge 1->2 is added to the frame that corresponds to the the nesting [ view nodes: #(1 2) ... ]

Does it make sense?

Cheers, Alexandre
