z
Z-coordinate value for 3D layouts and displays
type: double, default: 0.0, minimum: -MAXFLOAT, -1000
Deprecated: Use pos attribute, along with
dimen and/or dim to specify dimensions.
If the graph has
dim set to 3 (or more), neato will use a node's z value for
the z coordinate of its initial position if its pos attribute
is also defined.
Even if no z values are specified in the input, it is necessary to
declare a z attribute for nodes, e.g, using node[z=""] in order to get
z values on output. Thus, setting dim=3 but not declaring z will cause
neato -Tvrml to layout the graph in 3D but project the layout onto the
xy-plane for the rendering. If the z attribute is declared, the final
rendering will be in 3D.
