Techniques are disclosed for navigation in a hierarchical node structure. A first graphical element representing a parent node in a hierarchical node structure is displayed via a graphical user interface (GUI). One or more second graphical elements, each representing a first child node of the parent node, are further displayed via the GUI on a first imaginary curve adjacent to or at least partially surrounding the parent node. In response to a user selection of one of the first child nodes, one or more third graphical elements each representing a second child node of the first child node are displayed via the GUI on a second imaginary curve adjacent to or at least partially surrounding the selected child node.
