Custom {ggplot2} Coord layer

[trevorld]

• Probably possible to write a custom {ggplot2} Coord layer to add an explicit z-axis:

@trevorld I'm not aware of such examples. The x- and y-axes are pretty hardcoded in the internals of ggplot2, so I'd think it'd require extending a coord first to support the placement of a z-axis, at which point one can start extending an axis guide to render a z-axis.
