Additionally, you may want to play with the charge and length in the layout. Consider the following example: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= builder := RTGraphBuilder new. builder nodes shape: (RTEllipse new size: 20). builder edges connectTo: [ :c | c subclasses ]; useInLayout; shape: (RTLine new color: Color gray). builder layout force charge: -300; length: 20. builder addAll: Boolean allSuperclasses, Boolean withAllSubclasses. builder build. builder view -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= We give a repulsion of -300 to each node (which is what you want since nodes have to repulse each other), and you give a length of 20 pixel to each edge.
