Export grViz graph as SVG with V8

Use viz.js with V8 to get the diagram rendered as SVG in R instead of the browser.

Usage

export_svg(gv)

Arguments

gv

htmlwidget to render as SVG.

Value

string of SVG XML text.

Examples

if (FALSE) { # \dontrun{
 library(DiagrammeR)
 svg <- export_svg(grViz('digraph{a->b; c->a; c->b; c->d;}'))

 # on size of output using svg rather than unrendered grViz
 library(htmltools)
 html_print(HTML(svg))
} # }
