Broken CLI Graphs? (v0.5.1)

[jdiefen]

Something's happened since I last used the CLI. Has the website not been updated, or is everything breaking? Even something as simple as this:

graph LR
    C --> D

or

graph TD
    A-->B

Is giving me a completely blank PNG...not even a background. Just completely transparent with nothing shown.
Also, is this (from #153 ):

graph LR
    subgraph A
        B
    end
    style A fill:#f9f

supposed to give this .png?

Where is that extra A element coming from? I tried putting a semi-colon after the style line, but nothing changed.

Mermaid & PhantomJS are both updated to the newest version.

I think this is a result of lacking styling. I could replicate your issue and eliminating it by adding
-t ./dist/mermaid.css
to the command-line

Is this the way it's supposed to work? Is there any way the css could just be included by default if no css file is given? I feel that this issue would happen to just about everyone who's starting out by reading the documentation online.

I definitely got caught up by this, and I imagine many others will. Is there a reason why we shouldn't just use the default styles when generating a PNG file? Or is this a recent regression?

It seems like the default behaviour, which is to generate blank PNG files, is confusing.

I agree! @fardog is this something you could find time for? I am unsure how the paths to the css files would be calculated in the CLI when installed globally.

I've sent a PR to address the issue, tested it locally by using npm link to replace the globally installed version. I've also included a test of course :)

I'll review the posted PR after work and give it a +1 if it looks good
