There are features in Gramps Web that cannot be demonstrated using the demo instance of Gramps Web. Because it is designed to have the data mangled by anyone who visits, every couple of hours the site is reset back to defaults.

I think there is no good alternative to just manually creating a database, perhaps combined with some real genealogical data that is in the open domain.
