I am working with huge generated .dot graph file (not generated by me but by an application). Is it possible using graphviz to generate the graph showing only the nearest x branches to a node. This will make the graph more comprehensible instead of an extremely large mess.
There is a GVPR program named knbhd that seems to do what you want. On my Linux (fedora) system I found it here: /usr/share/graphviz/gvpr/knbhd.
It seemed to work with this commandline:
X=5; node="yournodename"
gvpr -a $X -a $node -f /usr/share/graphviz/gvpr/knbhd yourfile.gv
