I would argue the last "good" chart example, a chart of mass-shootings per president, is misleading as it compares four two-term presidents (Obama, W. Bush, Clinton, and Reagan) to a single-term president (H.W. Bush).
There is lies and there is statistics :). For more reading on the subject, I recommend Beautiful Evidence by E. Tufte. He's a classic when it comes to infoviz.
So this complains about not including the 0 on the y-axis but then complains about it in the national review global temp chart.<p>If you have an agenda it will show through, regardless of what you do. Both graphs accurately portray the data, but most of the public doesn't care to interpret graphs objectively.
