Display menu hierarchy as org chart?

Possible libraries:

• https://github.com/dabeng/OrgChart
• https://gojs.net/latest/samples/orgChartStatic.html - commercial, expensive
• https://naadydev.github.io/jhtree/
• https://github.com/wesnolte/jOrgChart

This is an interesting idea!

That being said, I can't see it being useful for everyone using the sitemap module, so I think it would make the most sense as either a sub-module (i.e.: in Sitemap's codebase), or as a separate contrib module in Sitemap's ecosystem.

Putting on my maintainer hat for a moment, I would be willing to accept it as a submodule, but I would want a good suite of automated tests in that case.

Whether it becomes part of the Sitemap codebase or not, I would welcome some input on how Sitemap could improve its public API (and - if possible - how we can test the Sitemap module's public API, i.e.: so that we can detect BC-breaks).

@damienmckenna, recently, @malcomio filed a new ticket with a similar goal — ✨ Provide option to display as a visual sitemap Active — and provided some code.

Would #3525996 suit your use-case? If so, would you be willing to provide feedback on that ticket?
