jgf-dot

Convert a json graph into a dot file for use with Graphviz and other visualizers

Command line

Install nodejs and run:

npm install -g jgf-dot

Then you can do the conversion using either:

cat graph.json | jgfdot > graph.dot
jgfdot graph.json > graph.dot

jgfdot

Reads a json graph from STDIN or file_name and outputs the Dot file to STDOUT

Docker

Install docker and run:

docker build -t jgfdot .
cat example/graph.json | docker run --rm --interactive jgfdot

Javascript API

You can also use the programmatic API to convert json graph objects to dot file strings

var toDot = require("jgf-dot");
 
var graph = require("./graph.json");
 
var fs = require("fs");
 
var dot = toDot(graph);
 
fs.writeFileSync("graph.dot", "utf8");

NOTE: Currently the graph isn't being valdated before it gets parsed, but that feature is on the todo list.
