I didn't make it myself. I found it on a website. I was
   surprised to see that I instantly agreed with most of it.
   Somebody did question me on it when I shared it elsewhere. They
   asked me "What about the Ethiopian Orthodox?" and I had to think
   about it. If I made this chart, I would put the Oriental
   Orthodox and Eastern Orthodox on parallel lines. I don't know
   how I would place Islam as I believe there are a number of
   movements within peoples who refer to themselves as Islamic,
   some of which are accurately Islam and some of whom stray from
   it but still use the name. But I lack some knowledge in that
   area.
