According to this page
a sample document `circ.tex' is included in the distribution
(meaning the AUCTeX distribution.)
Where is this file located? My operating system's 'search' facility doesn't find it. I'm concerned this might suggest my installation is faulty.
Operating system: macOS Sierra, Version 10.12.3
Emacs version: 25.1.1
AUCTeX version: 11.90.0
