That looks interesting. Would you say kheops is stable enough to 
be relied upon  by other projects? Any plans to make it into a 
dub package?

Since kheops is vector based it would be even nicer to be able to 
convert a cairo svg/pdf surface to kheops.

cairoD is indeed what ggplotd uses to produce the plot. And 
saving svg/png/pdf to disk is indeed very easy with cairo.
