really it was a very helpful diagram and the time i spent painstakingly making it in photoshop was actually useful in that it gave me time to really look at the diagram and see what it was i was trying to say with it and where it was accurate and where it was not.
when i was done with the diagram i printed it out and then set it before me as i wrote down exactly what i had come to realize as a result of drawing the diagram.
sometimes visual thinking really works.
