D3 nodes overlapping

Question

I'm using a modified version of the following example and everything works great so far.

What I am trying to do is to make the nodes bounce from each others and not overlap because I can't see the text and icons of a node if there is another on top of it. Is there a way to make this happen without modifying too much of code that works already? Maybe add something like enabling collision for the nodes?

好的，我似乎将charge设置为.charge（-300），通过将节点彼此推开来将节点分开。
