Claim 16:
17. A method of navigating a hierarchical electronic questionnaire, the method comprising:
providing a user interface (UI) via which:
at least a portion of the hierarchical electronic questionnaire is presented on a display device as a tree-based questionnaire map comprising a two-dimensional (2D) map, the tree-based questionnaire map having a plurality of nodes connected by a plurality of branches that do not intersect each other, the nodes of the plurality of nodes corresponding to questions;
a user input is received, via at least one user input device, indicative of a selection of at least one of the nodes; and
the question corresponding to the selected node is displayed and a user input indicative of an answer to the question corresponding to the selected node is received via the at least one user input device;

populating one or more nodes other than the selected node based on the selected node and/or the answer to the question corresponding to the selected node;
adjusting, via an input received via the at least one user input device, a length of the branches on the 2D map as the 2D map increases in size on the UI; and
adjusting, via an input received via the at least one user input device, the length between branches on the 2D map as the 2D map increases in size on the UI according to an original length of the branches and an exponential branching level.
