# Description

<!--- Please include a summary of the change and which issue is fixed.
Please also include relevant motivation and context. -->

This enables you to insert arbitrary dot inside the `digraph` element.
This can be used to style the dot file. For example:

with the file `fragment.dot` having the contents:

```
rankdir=LR
ranksep=0.01
dpi=300
node [shape=rect style=filled fillcolor="#8a3391" fontcolor="white" fontname="Arial"]
edge [fontname="Arial" fontcolor="#83a3391" penwidth=2]
```

You could then call

`pulumu stack graph --dot-fragment "$(<fragment.dot)" stack.dot`

Which could be in a command pipeline like

`pulumu stack graph --dot-fragment "$(<fragment.dot)" stack.dot && dot
-Tpng -O stack.dot && open stack.dot.png`

To generate and display a styled view of the graph without needing to
hand edit the dot file in the process.
