Abstract

A method of ordering visual objects presented on a display includes comparing visual objects to be placed in an overlapping condition and determining from the comparison the order in which the visual objects are to be placed. The visual objects are re-ordered and placed in the overlapping condition in accordance with the determination. Methods of creating connecting links joining source and destination visual objects as well as overlapping object and object-connecting tools are also provided.

2. The method of claim 1 wherein during said comparing, a metric of each visual object is compared to determine a relative size of each said visual object.

3. The method of claim 2 wherein during said determining, visual objects are placed in order from smallest to largest with smaller visual objects being placed in front of larger visual objects.

4. The method of claim 3 wherein said metric is the area of a rectangular region surrounding each visual object.
