Dependency graph visualization does not display arrows in chrome.

I am using the last released version of luigi 2.0.1 and I have find out that chrome does not display arrows in the D3 visualization.

My version of chrome is: 48.0.2564.116 (64-bit)

When I go to the Javascript console, I am getting the following error:

I'm seeing the same error on Chrome Version 49.0.2623.112 m (32-bit) with luigi==2.1.1

I'm just kinda guessing here, but D3 is mentioned within visualiserApp.js which was commited by @stephenpascoe as PR #1086 . Maybe he'd know what might be causing this.

I'm seeing the same now in Version 49.0.2623.87 (64-bit). The upstream project has a ticket for it (dagrejs/dagre-d3#202). I think it only needs an upgrade to dagre-d3.
