Strongly disagree with replacing bar charts by scattered points with arbitrary position on the horizontal axis (2 and 3). It is very difficult to disassociate horizontal proximity from vertical proximity, and the former is meaningless and distracting here.

Strongly disagree with your disagreement. The scattered points are very readable. They present more data, data that's simply missing from the bar charts. I always feel a little bit bad presenting, say, just a box and whisker plot when the original data is so much richer.

Interesting. I intuitively disregarded the horizontal placement of the dots at first sighting. Not sure why. The dot graphs are much easier for me to visually process and understand.
