Hello
I've added new features for the force based layout.You can change the gravity center, tell where you want to see your fixed nodes and so on.
I still have a bug with padding, and resizeStrategy, for example when you click on Example in the view.
Gofer it

package: 'RoassalForceBaseLayout';
load.
Try this :
---------------------------
"Preambule. It includes the initialization. "
| rawView view layout |
rawView := ROView new.
view := ROMondrianViewBuilder view: rawView.
"enter your script below"
"-------------"
"-------------"
view interaction on: ROMouseEnter do: [ :n |
| nodes |
nodes := view raw elementsFromModels: n element model allSubclasses.
ROHighlightElements on: nodes ].
view interaction on: ROMouseLeave do: [ :n |
| nodes |
nodes := view raw elementsFromModels: n element model allSubclasses.
ROUnhighlightElements on: nodes ].
view shape rectangle size: 10.
view nodes: (Collection withAllSubclasses).
view edgesFrom: #superclass.
layout := ROForceBasedLayout_N new.
layout fix: (view nodes last) at: 450@450;
gravityAt: 437@38 .
view layout: layout.
view applyLayout.
