1. A method comprising: receiving data representing a hierarchy, wherein the hierarchy comprises at least one set of sibling nodes and a respective parent node; generating, by a computing system comprising at least one processor, a condensed hierarchy, wherein generating the condensed hierarchy comprises: determining a grouping for the at least one set of sibling nodes; determining, based at least in part on the grouping for the at least one set of sibling nodes and based on one or more hierarchy condensation criteria, whether the at least one set of sibling nodes can be represented by the respective parent node, wherein the one or more hierarchy condensation criteria comprises a determination of risk; and responsive to determining that the at least one set of sibling nodes can be represented by the respective parent node, removing the at least one set of sibling nodes from the condensed hierarchy based at least in part on the determination of risk; and outputting, by the computing system, the condensed hierarchy for display.
