I'm not sure I understand the issue about the user repeatedly tweaking parameters for their data visualization. If anything, that is a reason notebooks are so nice. The repeated tweaks are due to the notebook format, its because that's an inherent part of the data visualization process, where the end result of a particular parameter choice is hard to predict how it will look with a given data set. So the same process would occur whether one was using a notebook or a script, but with a script it becomes much more cumbersome to actually see the result. In a notebook, the parameter tweaking for a data visualization is immediately followed by the result. I definitely agree with most of the other points though.
