make_svg_document_buffer_from_graph()

std::unique_ptr< std::string > dot::make_svg_document_buffer_from_graph ( const graph & g )

static

Convert G to graphviz source, attempt to invoke "dot -Tsvg" on it
as a subprocess, and get the SVG source from stdout, or nullptr
if there was a problem.

make_svg_from_graph()

std::unique_ptr< xml::node > dot::make_svg_from_graph

(

const graph &

g

)

Convert G to graphviz source, attempt to invoke "dot -Tsvg" on it
as a subprocess, and get the SVG source from stdout, and extract
the "svg" subtree as an xml::raw node.

Note that this
(a) invokes "dot" as a subprocess
(b) assumes that we trust the output from "dot".

Return nullptr if there was a problem.
