That's pretty accurate for the most part.
The scary thing is batshyt crazy Fox News for example is about as popular as the ones high up in the center who report far more objectively.
Meanwhile extreme left outlets are more niche.
The Far Right are highly popular echo chambers who accuse everyone else of being in echo chambers.
That being said, there is no doubt these organizations are in the "focus" business.
They need your attention so they can point it to where they want you to look.
That means you don't stop questioning things and motives from the more "objective" sources although mind the line between critical thinking and being a wahoo.
Things such as graphs like this should be questioned as well, such as the authors, who was involved with the research, etc.
