I think it's a nice way of demonstrating that if some variables have a 
mathematical relationship, that relationship works in more than one 
direction. A formula or an equation doens't demonstrate that quite so 
vividly. But drawing three lines and saying "mark two points and draw a 
line and you can always find the third point" makes it quite clear.

Well, I ended up staring at a Smith chart - and, obviously, wondering 
WTF is going on! And *that's* when I started reading about nomograms...
