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.
