13. The system of claim 9 , the method further comprising: accepting, at the electronic document editing device at a third time subsequent to the first time, a third editing command for a second two-dimensional object within the two-dimensional electronic document; and displaying, on the display device, a representation of an additional three-dimensional structure corresponding to the second two-dimensional object along with the three-dimensional representation of the first two-dimensional object, the additional three-dimensional structure extending along the third dimension from a third time point corresponding to the third time, the additional three-dimensional structure depicting at least one of the first dimension and the second dimension and representing time as a third dimension illustrated as being orthogonal to the first dimension and the second dimension, the additional three-dimensional structure representing first dimension components and second dimension components corresponding to the third editing command at the third time point and extending from the third time point.
