'Joy Plots' -- Great Plot Style for Visualizing Distributions on Discrete/Categorical or Multiple Continuous Variables

R doing what R does really, really, really, really, really, really, *R*eally well: visualization. Folks, this might be THE plot to use to visualize distributions of discrete/categorical variables or simultaneous distributions of multiple continuous variables, replacing or at least taking up a seat alongside the violin plots as the current best approach IMHO.

(EDIT: This plot style is named after the “Joy Division”, due to a similar graphic on one of their album covers. Not being at all familiar with Joy Division or their work, the name that comes to mind when I see this plot is “Misty Mountain Plot”, after the maps in “The Hobbit”)
