graphviz overlap=ortho: horizontal layout

Question

I've got an undirected graph made by graphviz tools (now i'm using sfdp):

    digraph structs {
    node [shape=Mrecord, URL="index_new.php?object=\N&overlap=false"];
    overlap = orthoxy;
    bgcolor=transparent;
    splines=true;
    rankdir=TB;
    node [fontname="Arial", fontsize=30, style=filled, fillcolor=chartreuse1, image="../common/img/monitor.png"]struct_swbposad91 [label = "sw-bposad9-1\n192.168.17.141\nC2960 "];
        node [fontname="Arial", fontsize=30, style=filled, fillcolor=chartreuse1, image="../common/img/monitor.png"]struct_swmedikov5fan [label = "sw-medikov5-fan\n192.168.34.134\n "];
        node [fontname="Arial", fontsize=30, style=filled, fillcolor=chartreuse1, image="../common/img/monitor.png"]struct_swlevash131 [label = "sw-levash13-1\n192.168.16.165\nC2960 "];
        node [fontname="Arial", fontsize=30, style=filled, fillcolor=deepskyblue]struct_swpolevsabirov45a [label = "sw-polevsabirov45a\n192.168.18.182\nS2300 "];
...lots of lines goes here...
struct_swkazan71:f450212->struct_swbmorsk181:f450213 [weight=1.2, dir=both, color=black, penwidth=5, arrowhead="empty", arrowtail="odot"];
        struct_swmikh171:f450222->struct_swbotk151:f450223 [weight=1.2, dir=both, color=black, penwidth=1, arrowhead="empty", arrowtail="odot"];

here is full code: http://pastebin.com/P3MKTCm2 (it's really large, sorry)

and the output is like this one: (part)

Problem: i need my graph to grow horizontaly instead of verticaly. Is there any way to get the layout like the one on the image, but "rotated" 90 degrees?

Answer 1

A couple of observations made while trying to make something out of the graph:

• The graph is not big, but the markup sure is redundant - I applied a little love and removed them so one can actually read it (see below)
• The ports used for the edges do not exist and graphviz generates a load of warnings. While the output is still generated, this is certainly not a good thing.
• This is a directed graph - digraph and -> are used for directed graphs.
• overlap=orthoxy seems to be deprecated:

The remaining allowed values of overlap correspond to algorithms which, at present, can produce bad aspect ratios. In addition, we deprecate the use of the "ortho*" and "portho*".

Below the output when simply using overlap=false with sfdp, ignoring all warnings and the missing images:

    overlap=false;
