[graalvm-users] Running ggplot2 from Interop

[Stepan]

Another thing is that ggplot2 plots must be printed to actually show 
them, so:

print(ggplot(mtcars, aes(x=wt, y=mpg)) + geom_point())

if you want to build the plot dynamically (not tested):

g <- ggplot(mtcars, aes(x=wt, y=mpg)
g <- g + geom_point()
print(g)
