This command line tool can convert between a graphlib JSON document and a dot file.
Install it globally with npm
npm install -g graphlib2dot
Simply pipe your JSON document into the program:
cat graph.json | graphlib2dot
Or specify a file:
graphlib2dot -f graph.json
You can also convert in the other direction:
cat graph.dot | dot2graphlib
dot2graphlib -f graph.dot
You can create a JSON representation of your graphlib Graph via
graphlib.json.write and deserialize them via graphlib.json.read. More info here.
