nl_tokens: sort nodes breadth ( ie top to bottom in a column ) if both nodes have circular links or both don t have circular links then sort by the top ( y0 ) of the node else push nodes that have top circular links to the top and nodes that have bottom circular links to the bottom
pl_tokens: function ascendingBreadth ( a , b ) { if ( a . partOfCycle === b . partOfCycle ) { return a . y0 - b . y0 } else { if ( a . circularLinkType === 'top' || b . circularLinkType === 'bottom' ) { return - 1 } else { <mask> 1 } } }
