Is this graph correct on expiration and inhalation?

Yes.

The common graph that is used is:

But yes

DesertMedic66's graph is essentially what yours in showing, but a drawn out version to include all phases in ventilation, hope that helps.

The graph that @DesertMedic66 posted, with the labeled phases, is what you'll want to reference. That's how it's explained in every class or workshop that covers capno.

Want to make it really simple?

"Remember, the patient is blowing up the waveform, like they are blowing up a balloon". (How I teach it to firefighters.)

thanks guys.

And for the shark-fin, the balloon can't empty easily, I suppose?
I like this analogy, actually -- pretty intuitive!

I actually say, "See how this shark fin waveform looks squeezed? Remember that it's hard to squeeze out the air."

Sometimes the simple things stick with you.

Works for me!

Definitely correct. Do you know why they call it "peak" end tidal? Other than the fact that it's the highest point on the waveform Why is there a gradual accelerating waveform?
