sink=vertex

specify a main sink for the network. If a sink is specified, then a source must also be given.

source=vertex

specify a main source for the network. If a source is specified then a sink must also be given.

orientation="horizontal" or "vertical"

layout the network left to right, or top to bottom respectively. The default is "vertical".

The network layout method renders the Graph as a network starting from a source and ending at a sink that are either given, or automatically determined by IsNetwork.

This layout method works only in two dimensions.

$\mathrm{DrawGraph}\left(G\,\mathrm{layout}=\mathrm{network}\right)$
