Describe in detail the ways in which the visualization violates graphical integrity and excellence:

I swear I could not find any graphs on the site. Perhaps I was just super unlucky. Anyway, I decided to google up "foxnews graphs" instead and found this. This violates graphical integrity and excellence because of how much content is going on other than the data. The data-ink ratio is rather low. Also, this violates graphical integrity because of the scaling on the Y-axis. At first glance, it would seem as though there is a huge change between 2009 and 2011. However, in terms of tens of millions of dollars, the actual change is not that significant.
