rotate=90 graph attribute does not set the rotation

[reregaga]

rotate=90 graph attribute does not set the rotation, instead the rendered image disappears during typing this attribute or if you refresh the page, the graph is drawn as if without the rotate attribute.

Example:

digraph {
    //rotate=90 //uncomment
    a[width=2]
}

The problem is in translateZoomBehaviorTransform which doesn't handle rotation, but assumes it is zero. If the call to that function is removed, the problem doesn't occur.

This means that a workaorund when using d3-graphviz directly is to disable zooming with .zoom(false). Unfortunatley there's no way to do this in the Graphviz Visual Editor for which this problem was originally reported.

There was also a similar problem with transitions. See #328 for details.
