Years look off
X axis isn't long enough to show the long tail of production.
Seems pretty USA centric. Not world centric. USA production peaked a long time ago.

Looks like it was set up as a lesson for students and deliberately way off on timing to avoid controversy; my best guess.

No value is given to the numbers on the anual production axis so its not showing any true assessment.

Its for teaching.

The chart you want which is more impressive as an example is the cumulative which will be a backwards stretched out S. You can argue easily that any finite non-renewable resource will have a cumulative production curve that probably looks alot like that logistic curve. When you take the derivative of that you get something that looks alot like a hubbert curve with a definite peak of production. It is a nice object lesson about alot of things that happen in the world and you do not really need to use any specific numbers at all. They just need to understand the cumulative curve and the idea of rate of change. I am not sure why the derivative of the gaussian is interesting at all it tells you what is already obvious from the gaussian itself.
