The easiest way I've found is to draw the type of object I want directly in Graffle and then copy as AppleScript and paste into TextEdit, Script Editor, or wherever.
To do this, select your object(s). Then choose "Copy As" from the Edit menu and "AppleScript" from the sub-menu that pops out.
Obviously, this is more a trial-error approach than an exhaustive list, but if you know what you want, it's not _too_ bad.
