English: Issue-based information system (IBIS) rhetorical rules diagram that has three nodes (circles labeled "issue", "position", "argument") connected by directed edges (arrows) that show which nodes are permitted to lead to other nodes in IBIS notation. IBIS as typically used has three basic elements (or kinds of nodes, labeled "issue", "position", "argument") and a limited set of ways that the nodes may be connected. Issues (questions) can be associated with any node. Positions (answers) can be associated only with issues. Arguments can be associated with positions but not with questions.
