I believe those basic attributes are only used if there's no RTF, so  
I'm pretty certain you'd have to write the RTF.

That bounding box calculation is somewhat complicated:  I know we've  
had to address a number of issues with Japanese text, for example.   
But for simple cases I think it's based on -sizeWithAttributes: plus  
margins.

However, you could just set the size to {1, 1} and turn on FitText  
and Resize Flow on the shape to make OmniGraffle figure out the size  
itself:

	<key>FitText</key>
	<string>YES</string>
	<key>Flow</key>
	<string>Resize</string>

Alternatively, you might explore writing a document using the  
GraphViz DOT file format <http://www.research.att.com/sw/tools/ 
graphviz/>.  OmniGraffle doesn't support the full range of DOT  
commands (the commands which are supported are document in  
OmniGraffle's Help), but it's a standard file format which is better  
documented.

I'd certainly use it!  (I usually use R's pdf() device right now, and  
I'd love to be able to make that output look better by using  
OmniGraffle.)
