A relationship map includes multiple nodes that display related information from node to node in a tree-like, hierarchical fashion. The relationship map associates a formula with a particular node of the relationship map. The relationship map also associates range information with the particular node, the range information indicating a range of nodes to which the formula should be applied. The range information may indicate whether the nodes in the range extend leafward or rootward from the particular node in the relationship map. The relationship map displays the particular node updated with result information that a relationship map generator generates when applying the formula to the nodes specified by the range information.
