Would you be surprised to find out that the figures above were made in Stata? I discover the work of Daniel Bischof about a year ago and it has changed the way I think about Stata figures. I have been a long time user of ggplot2, the graphing R package by R Guru Hadley Wickham. Some of my publication figures using ggplot2 are dozens of lines long. I enjoy fiddling with every aspect of the aesthetic to make a perfectly clear visualization.
