The original ranking algorithm was fairly complex, and tried to produce a very compact ranking. This could lead to some anomalies (at least to me), such as having an edge...

I'm not understanding your approach. How do the position information and edge properties specify the drawing? In particular, the routing of the back edge 6->2 can got either to the...

Not exactly. The problem is that you have the same node in two incompatible clusters, i.e., non-nested. The old ranking works because it quietly ignores one of the nodes in...

If the packmode attribute is set, this is actually checked and reported, but it doesn't exit with an error.

(Sorry for taking so long to respond.) This is not a bug but the output is working as specified: *The text consists of the n bytes following '-'*. Graphviz takes...

Does this also occur on Linux, because that is where I encountered it?

I believe it is necessary to call gvFreeLayout. This documented in http://www.graphviz.org/doc/libguide/libguide.pdf.

Technically, this is not a bug. For convenience, the grammar allows space characters immediately within the top-level quotes. This way, you can have a label like `<

The problem is the documentation. Partly, it is not clear; and partly it is out of date given the "newer" text elements. Basically, there are two cases. If the label...

Roughly, the problem is arises because of the small size of the nodes and the small separation. There is an error in the code that generates the polygon that is...
