Bertillon introduced the first standardized system of causes of death, and made many statistical charts and maps.
This lovely one shows movement of travelers through Paris in 1889, using flow lines overlaid on the city map, bar charts and a pie chart legend.

For me, ggview's most useful space is when I am developing a figure in RStudio with a lot of tweaking, and that figure is eventually going to go into a specific dimension output. So I don't need to be writing out and refreshing the figure to be checking annotations etc as I create them.

I love to see head-to-head comparisons of one graph type to a quite different one for the same data! (Or should that be toe-to-toe?)
