Please read the manual:

           open_graph "foo:0"  connects to the display foo:0 and creates a
             window with the default geometry 
           open_graph "foo:0 300x100+50-0"  connects to the display foo:0
             and creates a window 300 pixels wide by 100 pixels tall, at
             location (50,0) 
           open_graph " 300x100+50-0"  connects to the default display and
             creates a window 300 pixels wide by 100 pixels tall, at
             location (50,0) 
           open_graph ""  connects to the default display and creates a
             window with the default geometry. 

(this is specific to Unix).

Cheers,
