A chain visualization represents first, second and third hierarchical data items from a database. The second data item descends from the first. The third descends from the second. The visualization shows an ancestors chain and a descendants chain. It has an active item location where the chains meet. The visualization shows a card linked to the ancestors chain for the first data item, a card in the active item location for the second data item, and a card linked to the descendants chain for the third data item. Users may navigate upwards or downwards in the hierarchy by activating any card outside the active item location. Users may stack cards to save screen space, and users may scroll to view different parts of the hierarchy. Users may edit information from data items represented by the cards.
