Added an option to as_vegaspec(), single_view to indicate to collapse a single-layer ggplot2 object into a single-view Vega-Lite specification. This makes it easier to add selections and conditional encodings using {vlbuildr} (#70).
Added support for ggplot2::coord_flip().
Added support for basic scatterplots (ggplot2::geom_point()), not faceted.
Added a NEWS.md file to track changes to the package.
