没有边缘的节点的GraphViz Dot布局

Question

I'm calculating quite big layouts with the GraphViz dot layout. My source structure is a graph where some nodes are connected and others not. The layout for the connected nodes is perfect, but dot alignes all other nodes in a straight row, which leads to a quite huge length of the output. Is there any change to get rid of this?

Answer 1

There is a program called unflatten in the Graphviz suite that can be used for this. An example of usage:

unflatten -c 2 graph.dot | dot -Tpng -o graph.png

where you tell unflatten to chain disconnected nodes up to a length of 2. This will create invisible edges that prevent the nodes from being lined up as you describe. For more details, see the documentation .
