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 "];

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?
A couple of observations made while trying to make something out of the graph:
digraphand->are used for directed graphs.overlap=orthoxyseems to be deprecated:Below the output when simply using
overlap=falsewith sfdp, ignoring all warnings and the missing images:And here the same with dot:
