Broken Examples

[sholtomaud]

Having trouble with many of the Gantt examples:

>mermaid graphTD.mmd

Produces the following response:

PHANTOM ERROR: TypeError: 'null' is not an object (evaluating 'oDOM.documentElement.attributes.getNamedItem('height').value')
TRACE:

Sorry to hear that.

May I ask what version of mermaid you are running and perhaps a pointer to a broken example.

>mermaid --version
0.4.0

I think you are lacking a gantt config. Look at issue number #158 for more info.

I think that there should be a default config though in order to avoid these kind problems in the future. In the light of #158, I will close this issue as a duplicate. Please let me know if this works out.
