graphviz dot code blocks does not render

[pujfei]

Issue Type: Bug

The "Markdown Preview" extension works well with the graphviz language while the "Markdown Preview Enhanced" extension (which claims an enhanced one to the former) does not.

Quite weird.

The code block looks like below:

digraph finite_state_machine {
    rankdir=LR;
    size="8,5"

    node [shape = doublecircle]; S;
    node [shape = point ]; qi

    node [shape = circle];
    qi -> S;
    S  -> q1 [ label = "a" ];
    S  -> S  [ label = "a" ];
    q1 -> S  [ label = "a" ];
    q1 -> q2 [ label = "ddb" ];
    q2 -> q1 [ label = "b" ];
    q2 -> q2 [ label = "b" ];
}

Extension version: 0.5.2 VS Code version: Code - Insiders 1.44.0-insider (2aae1f26c72891c399f860409176fe435a154b13, 2020-04-07T21:41:19.483Z) OS version: Windows_NT x64 10.0.18363

I found a work-around: the dot code block ```dot works! I'm using v 0.5.3 on vscode 1.44.0 on Windows 10.

Yeah! Great job! Magical thing! This method does work!

Perhaps the enhanced version just used an alias of '.dot' for the real format '.graphviz'.

Is there a convention or standard for the markdown block format? I think developers do need one. Standard is a good thing.
