Hi, Subversion tracks the evolution of a tree structure along the time. Changes can be represented in a bi-dimensional system coordinates: time vs space.
The vertical coordinate (space) is the path of the items of the tree structure and the horizontal coordinate (time) is the revision number. Example: http://www.svnflash.com/images/svnflash/subversion_3d.png Changes of the tree structure along the time can be represented as dots (red in the example) in that system coordinates. Has some sense adding a 3rd coordinate meaning something unknown for me at the present? Thanks and sorry for so abstract question.
