Employing visualisation for the representation of complex relationships within data. The collapsible text index contains a component G with multiple parentage; it is necessary to provide two separate text entries to show descent from each parent. The corresponding directed acyclic graph (DAG) could either represent the data with two separate nodes (clones) or display the node G only once, with a link to it from each parent. Advantages in the latter representation include a reduction in the amount of data displayed to users.
