/sig cli
What would you like to be added:
A command to dump the .spdx DAG as a dotlang .dot file for easy visualization with graphviz.
Why is this needed:
The current .spdx visualization command outline is limited by the cli environment the result is rendered in. It is unable to appropriately display the DAG when a node has 2 or more parents. Consider the following example:

This file creates a graph that looks something like this
However when visualized with document outline the output is like this.

This is missleading.
- Python appears twice in the graph even though there is only one package with that name.
- In the gnome branch of the graph sqlite does not appear despite being a direct descendant of python.
Outputting the graph as a dot file will allow for the use of third party tools such as graph-viz to provide a more accurate visualization. Dot is also used for representing graphs in a variety of other applications. I'm sure other uses of this feature can be found.
