Save a ggsql spec to a file

This function renders a specification and returns it either as a Vegalite json string, an SVG or a PNG. For the latter two, the Vegalite JSON is rendered to SVG using the V8 package and, potentially, converted to PNG using the rsvg package.

Usage

ggsql_save(spec, file, width = 600, height = 400)

Arguments

spec

A Spec object returned by ggsql_execute().

file

Output file path. Extension determines format: .svg, .png, or .json.

width

Width in pixels.

height

Height in pixels.

Value

file, invisibly.

Examples

reader <- duckdb_reader()
ggsql_register(reader, mtcars, "cars")
spec <- ggsql_execute(reader,
  "SELECT * FROM cars VISUALISE mpg AS x, disp AS y DRAW point"
)
svg_file <- tempfile(fileext = ".svg")
ggsql_save(spec, svg_file)
