A graph including a hub corresponding to a selected or primary item or keyword and a plurality of nodes corresponding to related or secondary items or keywords may be used to express the relationships between items or keywords. Optionally, the graph may include a plurality of tethers extending between the hub and each of the nodes. When used in Internet-based commerce, the relationship graph may recommend related secondary items to a customer who is searching for a primary item, and may further express the degree of relationship between the primary item and each of the secondary items. When the customer selects a node corresponding to a secondary item, a new set of nodes corresponding to tertiary items related to the selected secondary item may be displayed. In this manner, the relationships between the primary item and more distant tertiary items may also be represented to the customer. |
