My boss provided me the attached network diagram, saying that it was pretty good but he thought there was probably a bit of room for improvement.
This is not a joke - we have actually been using this as our network diagram and it is in our network documentation.

I have seen a couple different tools online that could be used to improve this. Having never used one before, I am finding it difficult to evaluate them for suitability and ease of use.
Does anyone have any best practices or input on how to approach this for someone doing this for the first time?
