Feature request @facet_grid and @facet_wrap

[dpabon]

Hi,

Thanks for the wonderful work with the package! I wondered if you have plans to include facets functionality.

Cheers,
Daniel

I do - they're a little trickier to implement than you might think at first glance, but I plan to implement them eventually. If anyone wants to give this a go, the equivalent AoG functionality is through a mapping() layer with row and col kwargs

Initial implementation of this feature is complete!

@ggplot(penguins) + 
    @geom_point(aes(x = bill_length_mm,
                    y = bill_depth_mm)) +
    @facet_grid(rows = species, cols = island)

@ggplot(penguins) +
    @geom_point(aes(x = bill_length_mm,
                    y = bill_depth_mm)) +
    @facet_wrap(species)
