Need software to 'beautify' 2D chemical graphs

 Are there any software packages that can take as input a connection
 table and produce a 'regular' (i.e. aesthetically pleasing) 2D chemical
 graph which can be EXPORTED to third party applications via a standard
 2D coordinate file? The term 'regular' refers to graphs with standard
 bond lengths and angles, ring geometries etc. In other words, I am
 looking for algorithms that produce a publication-quality 2D representation
 of a molecule which is consistent with standard chemical drawing
 conventions.
 A few comments on the degree of sophistication of those programs would
 also be useful. I know from my LHASA days that this is NOT a trivial
 problem, particularly if you are dealing with complex fused/bridged
 systems.
 Thanks for your help.
