I would like to construct a minimal reproducible example to illustrate a question here on
gis.stackexchange.com. Ideally, that example would reference data that's easily accessible to any ArcGIS user, without requiring that they download data from some external site.
Are there example feature classes (and/or data of other types) that I can rely on every user having access to as part of their ArcGIS installation? If so, are some of those frequently used in examples, and so familiar to many users?
