No one is saying that we're not getting better at producing food.
But this graph does not show food production efficiency, it shows agricultural products' overall monetary value...
As such, saying it is all attributed to efficiency increase in farming from this visualization is pure assumption. There are many more factors which contribute to monetrary value, other than productivity or efficiency.

It's as good as any other shorthand. Weight, volume and calories are all insufficient, as different crops output different values. $ value of an agricultural commodity index hasn't changed radically over the decades.

It's not good enough.
And it sure as hell does not give a clear picture, as hiking prices would have the exact same effect than production efficiency.
And from this graph, you have no way of distinguishing which reason it actually is.
That's why it is a wrong metric to choose.

What would you prefer? Corn or wheat yields as a proxy?

Overall yield, either average or median of all grown crops, in tonnes or calories, for example.
To show efficiency, possibly along with water usage needed and normalized per square kilometer.
