There's not a way to incorporate graphical sitemaps, but we do allow HTML documents in the knowlege base.
They might not be that usefule, though, since the Knowledge Base agent doesn't consistently send links in messages. So the bot might be able to say "The About page is in the home page nav bar" it can't say "Click [here]() for the about page!")
