I have an undirected graph created using graphviz tools (now I use 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"]; ...lots of lines goes here...
here is the full code: http://pastebin.com/P3MKTCm2 (this is really big, sorry)
and the result is as follows: (part)

Problem: I need my chart to grow horizontally, not vertically. Is there a way to get a layout like the one in the image, but โrotatedโ 90 degrees?
