It looks like Google has an API that will help build one: https://developers.google.com/chart/interactive/docs/gallery/orgchart
There are a ton more out there as well. Some Free, some paid.
As is usual any of these web integrations, a FM dev could get the data from FM formatted in the proper way and place it into this code and render it in a web viewer.
This looks interesting. I'm going to play with one of these and try to get it set up.

.. I only require ... create and print
