They're the single best example of why bar charts need to die that I think I've ever encountered. Particularly in biology, where you get two bars with maybe two error bars between them and the inevitable "*" – at best, something that conveys four independent numbers, badly; at worst, actively misleading. I'm very much with Tufte on the "data-ink ratio" being a good metric for a plot: violin plots have a lot of data and surprisingly little ink.
