Can you define "not realistic or cost effective"? I expect it would be
possible to create an org chart with an Access report. However, handling
multiple levels of employees and lots of unknowns would take much more
resources than purchasing Visio or some other program.
If this type of report was even just a little difficult I would expect
someone would have done it. I have considered giving this a try as a "for
fun" project but it's been on the back burner for a long time since I expect
it would take quite a few hours to make a report that can handle a medium
sized company.
