GOLEM interactively displays the structure of the GO hierarchy in the neighborhood of a selected term. Searching for the GO term "calyx development" displays the term, all child nodes, and all paths to the root node. The selected term and all incident edges are highlighted. Clicking on a node displays a popup menu that allows the user to dynamically browse the GO graph.
