[question] How to exclude tool_requires from graph info output

### What is your question?

Hey,

I would like to create a graph visualization using `graph info .. --format=dot ..`. We have defined some tool_requires in the host profile to apply them to the every package. The resulting graph visualization is now really a mess since every package is pointing to those tool_requires.

Is there a way to hide tool_requires for the graph output?

Thank you very much!
