unconnected nodes drifting infinitely away

[RealmX1]

When dragging any node, all other nodes unconnected to it drift away without any bounding force pulling back together.

It seems that most if not all of the examples shows such property. (especially obvious when trying the final example where you can create node and edges by yourself.

Is this intentional by design? Is there a way to set a bounding force that prevent unconnected nodes from drifting too far?

Try setting x and y forces: https://d3js.org/d3-force/center#center_x. For example:

    Graph
      .d3Force('x', d3.forceX(0).strength(0.02))
      .d3Force('y', d3.forceY(0).strength(0.02))
