Issue #6 : fixed some calls to “sys”
-
Issue #7 : Fixed so it can be installed on v0.8 (by Patrik Henningsson <github.com/pahen>)
-
Tiny corrections
-

Major correction in parse : error callback now take three arguments : code, stdout, stderr
-
Major bugs corrections

parse now accept a file or a script
-
Update render (see tests/hello.js)

Add attributs to addNode and addEdge
-
Add parser (see tests/parse.js)
-
Added the ability to render in-memory (without writing to the filesystem) (By Mathieu Ravaux)
-
Rewrite output method
-
Initial version
A basic example
var util = require('util'),
graphviz = require('graphviz');
// Create digraph G
var g = graphviz.digraph("G");
// Add node (ID: Hello)
var n1 = g.addNode( "Hello", {"color" : "blue"} );
n1.set( "style", "filled" );
// Add node (ID: World)
g.addNode( "World" );
// Add edge between the two nodes
var e = g.addEdge( n1, "World" );
e.set( "color", "red" );
// Print the dot script
console.log( g.to_dot() );
// Set GraphViz path (if not in your path)
g.setGraphVizPath( "/usr/local/bin" );
// Generate a PNG output
g.output( "png", "test01.png" );
$ cd ~/.node_libraries $ git clone git://github.com/glejeune/node-graphviz.git
Or :
$ npm install graphviz
You also need to install GraphViz
Install node-jake and dox then run
