8. The machine-assisted method of claim 1 , the method comprising: displaying a two-dimensional (2D) graphical representation of a chart comprising the graphical representation of a hierarchical network of graphical nodes on a 2D display comprising the idea map window; rotating the 2D graphical representation of the chart about at least one axis to obtain a virtual three-dimensional (3D) graphical representation of the chart; displaying the virtual 3D graphical representation of the chart on the 2D display; and permitting a user to further rotate the virtual 3D graphical representation of the chart about a vertical axis in the virtual 3D graphical representation of the chart, the vertical axis extending vertically through a specified node in the virtual 3D graphical representation of the chart.
