No, but you could base it on my plugin that does the same thing for networks of users
However, I’m not sure how interesting network of tags would be, could you please elaborate on the relationships you are trying to depict?
What’s helpful about it? (apart from it being potentially pleasant abstract art?)
Are you proposing to show a connection when tags are added alongside others on the same topic? And the strength of lines would depict the number of times this occurs?
