WebFeb 16, 2011 · 'Size' can be used with the 'ratio' parameter (the layout aspect ratio) to manipulate the configuration. 'Ratio' takes a float (e.g., ratio = "2.0") or 'auto' or 'fill'. (The latter tells graphviz to fill use the entire graph region alloted by 'size'. The parameters that have the greatest effect on graph configuration are 'nodesep' and 'ranksep'.

WebTo achieve this, Graphviz must scale the layout independently in each dimension. It's smart enough to scale the layout and not the image, so the image isn't distorted per se, but depending upon how different your requested aspect ratio is from the layout's "natural" aspect ratio the horizontal vs. vertical spacing may look a little weird.
