This is an example of the effect you can generate by playing with the forceLink parameters and the forceManyBody parameters.

This graph radially expands. Try dragging it around - nodes will stay where you put them but the rest will expand outwards.

This effect can be created in two steps:

• Set the forceLink strength to 0. This removes the link force while maintaining the lines between nodes.
• Set the charge to a small negative number.

It’s a bit useless in this particular example, but interesting applications could arise from this effect. See if you can come up with any!
