R Graph Gallery
The nice thing of this gallery is that you can get the sources of all examples, so this can be a good starting point for your own custom graphics in R.
There is a similar page - not so sleek - at http://zoonek2.free.fr/UNIX/48_R/04.html which is a bit more instructive.
None of the pages raise the question whether the presented graphics are useful though ...






I just skimmed over the second source. Did you borrow the "The Good"
example of May 2005 from this site, or vice versa, or was this parallel
development?

I wasn't aware of this plot, but the sequence from the barcharts to the dotplot nicely explains how you would stepwise improve the plot. The more exploratory way to look at that feature would be to use parallel boxplots and the alternate selection of the two years, but I did decide to stick with a display which shows single values and no summaries.
