Did you happen to notice whether the D trans light on the dash was
blinking?

Did you turn the car off and turn it back on to see if that cured it?

Are you sure it was fluctuating wildly like THAT, and not simply
between, say, 500rpm and 1500rpm? maybe 2000rpm?

you're under warranty, which is good. It could be transmission related.
Maybe Honda's infamous auto transmission technology has hit you where it
hurts.

On the other hand, if you've exaggerated the symptoms, it could be an
idle air control valve. That apparently is a VERY common failure in
Hondas (I've had two fail, both on the same car, in 7 years; dealership
isn't at all surprised).
