A problem I find with all of these is how can I render and publish the results somewhere on our corporate infra for everyone to see? And then, how do I ensure that the diagram-as-code in the repository is synced with that published render?

For example, at $work we use Confluence for documentation - I just don't see any of the solutions mentioned in this thread as being compatible with deploying diagrams to confluence, or indeed any type of CMS. It seems that at a minimum you need some bespoke docs rendering pipeline in every repository which spits our rendered docs and diagrams to some other platform?

How does everyone else solve this?
