The scroll view will set its scrolling range based on the size of the frame of its embedded document view, which is the view that you draw into. So there’s no need to set a document size in IB. Just make the document view an instance of your custom view class (drag in a Custom View object, set it to your class, then do Embed In Scroll View).
At runtime when you load the data your view can calculate how large it needs to be and set its frame rect appropriately. The scroll view will detect that and change the scroll range.
One warning about extremely large views is that at some point you will run into floating-point rounding errors, since AppKit and CoreGraphics coords are 32-bit floats and have only 24 bits of precision. Still, that should get you to millions of pixels before the coords stop being pixel-accurate.
