Function graphviz::render

pub fn render<'a, N, E, G, W>(g: &'a G, w: &mut W) -> Result<()> where
    N: Clone + 'a,
    E: Clone + 'a,
    G: Labeller<'a, Node = N, Edge = E> + GraphWalk<'a, Node = N, Edge = E>,
    W: Write, 

Renders directed graph g into the writer w in DOT syntax. (Simple wrapper around render_opts that passes a default set of options.)
