VRML
Virtual Reality Modeling Language
Outputs graphs in the VRML format.
To get a 3D embedding, nodes must have a z
attribute. These can either be supplied as part of the input graph, or
be generated by neato provided dim=3
and at least one node has a z value.
Line segments are drawn as cylinders.
In general, VRML output relies on having the PNG library to produce images
used to texture-fill the node shapes. However, if
shape=point,
a node is drawn as a 3D sphere.
Example: simple graph, rendered with
-Tvrml
$ echo 'digraph { a->b }' | dot -Tvrml
