It has been a good long while since I looked at Tukey, but what I took away from his body of work back then (setting the FFT algorithm aside) is that even the simplest tools can be used to reveal a lot about data (which he then amply illustrated in that book you display, e.g. stem-leaf plots). Just like Tufte, he does not strike me as the sort who'd surrender his capability to think and make sense of things to the computer.
