[EM] re: diagrams

For what it's worth, I drew up a pretty simplistic diagram to make 
demonstrations of how a cycle can happen in election results:

(available in SVG format as well)

It's a simple triangle with a bunch of dots around it.  A majority of the dots 
are closer to B than A, C than B, and A than C.

I have also used even simpler diagrams (not online) with dots bunched around 
three points on a line, heavier on the edges than in the middle, to 
demonstrate a situation where IRV fails.  

I find that for some visual thinkers the diagrams really help their 
understanding.
