Usage

#
# import data from csv file.
#

$ cat <<EOL | sgviz import --host
foo-host01,192.168.0.1
foo-host02,192.168.0.2
bar-vserver,10.0.0.1
EOL

$ cat <<EOL | sgviz import --group
group,hostname
foo,foo-host01
foo,foo-host02
bar.example.com,bar-vserver
EOL

$ cat <<EOL | sgviz import --policy
src,dst,port,desc
foo,bar.example.com,8080,'foo to bar.example.com:8080'
EOL

#
# export readable csv format.
#
$ sgviz host
foo-host01,192.168.0.1,bar-vserver,10.0.0.1,8080,tcp
foo-host02,192.168.0.2,bar-vserver,10.0.0.1,8080,tcp

$ sgviz policy
foo,bar.example.com,8080,tcp

#
# visualize dot lang.

$ sgviz policy | sgviz graph
digraph {
  "foo" -> "bar.example.com"
}

$ sgviz policy | sgviz graph | dot -Tsvg > example.svg
