\title{Render a laid out graph object}
\description{
  This method uses the \code{renderInfo} slot of a graph object to
  render it on a plotting device.
}
\usage{
\S4method{renderGraph}{graph}(x, drawNodes, drawEdges, graph.pars)
}
\arguments{
  \item{x}{An object derived from class \code{graph}}
  \item{drawNodes}{A function that is used for the node rendering. The
    details of its API are still undecided. Defaults to
    \code{renderNodes}}
  \item{drawEdges}{A function that is used for the edge
    rendering. Defaults to \code{renderNodes}}
  \item{graph.pars}{A list of rendering paramters to use as default}
  \item{\dots}{further arguments}
}
\details{
  This method can render graph objects that have previously been laid
  out using the function \code{\link{layoutGraph}}. The details for user
  defined node drawing remain to be decided.
}
\value{
  An object derived from class \code{graph} with information about the
  coordinates of the nodes in the coordinate system of the plotting
  device added to the \code{renderInfo} slot.
