But what I need is the ability to create links between entities (from father to mother) and links between nodes and other links (from child to the father-mother link). Currently I don't have a fixed data schema for this. I've chosen d3.js for this because it

Is there a way to get a child element to follow its parent? The problem is that if there is only one child and the parent has a huge text to it, the position of the connector becomes really bad.
