VegaLite.jl equivalent of `facet_wrap`?

plotting
#1

is there a way to wrap around the panels of multiple plots (similar to `facet_wrap in ggplot2)? For example would it be possible to arrange the Anscombe’s quartet plot shown in the docs (http://fredo-dedup.github.io/VegaLite.jl/stable/examples/examples_faceting/) in two rows and two columns?

I tried the following (trying to adapt the syntax from https://vega.github.io/vega-lite/examples/trellis_barley.html) but it doesn’t work:

using VegaLite, VegaDatasets
anscombe = dataset("anscombe")
p = anscombe |> @vlplot(mark="point",
                      columns=2,
                      encoding={
                      facet={field="Series", typ="nominal"},
                      x={:X, scale={zero=false}},
                      y={:Y, scale={zero=false}},
                      }
                      )

This is coming in the next version of Vega-lite, which I believe is getting close to being released. We’ll then need to update VegaLite.jl to target it, but I don’t expect that to be too much work.

thanks, good to know this feature is being implemented
