Too bad this chart doesn't show other types of dishonesty, like editing the way someone looks to make them appear unhinged. I know foxnews and cnn are guilty of this. In my opinion this chart gives too much credit to corporate news networks. If you have 24 hours of "news" everyday you are bound to tell truths. What matters is what are they dishonest about.
I've seen this before and appreciate it. If I remember correctly, they have to put out a couple of versions because not all the sites and be listed at the same time. I think they are wrong on Huffington Post. It is farther left.
This is the most recent version, apparently they've been putting it out for years.
