Forcedirected not separating nodes

Attached are two screenshots, one from Gojs and another using an alternative (that doesnt scale too well). As you can see the other one separates nodes really well and determines a layout with fewest crossed links. How can I achieve something similar with Gojs?

I think you need to adjust the parameters of the ForceDirectedLayout that you are using. How is it currently defined? You might want to increase its defaultSpringLength or decrease its defaultSpringStiffness.
