Basic example doesn't work

[jgauffin]

The basic example on the first page doesn't work:

var sigRoot = document.getElementById('sig');
var sigInst = sigma.init(sigRoot);
sigInst.addNode('hello',{
  label: 'Hello',
  color: '#ff0000'
}).addNode('world',{
  label: 'World !',
  color: '#00ff00'
}).addEdge('hello_world','hello','world').draw();

The nodes are not being layedout but are put at the same position.

See also #44 -- the example from the README in the repository works better.

So sigma can't layout nodes for you?

Even with x and y coordinates as specified in the README, the nodes are being displayed on top of each other for me.

Anyone had success with the basic example ?
For me it throw the error on Chrome's console: Uncaught Error: Edge's target "undefined" does not exist yet.
