How to make a boxplot in Sage?

edit

Here are some examples. To find these, I went to sagenb.org, clicked on "Browse published worksheets", then in the search box in the upper right, typed "boxplot" and clicked the search button.

Not an answer! Just copying one of the examples linked in Jason's post in case sagenb gets too slow at times.

data1=[1,2,2,2,1,1,2,2,2,2,2,3,3,3,3,3,3,3,4,4,4,3,3,3,4,5,5,10]
data2=[5,4,4,4,4,3,3,3,3,3,3,3,3,3,2,2,2,2,5,5,5,5,5,6,6,6,6,6,6] 

r.png()
r.boxplot(data1,data2)
r.dev_off()
