Draw a labelled sectioned graph [closed]

What would be the best way to recreate this in a LaTex environment? I have attempted to use pgfplots but having read through the documentation am still lost on how to start.

• Welcome to TeX.SX! It depends on how accurate the curve should be. I assume it is not a real plot, but the curve rather roughly depicts some sort of development. In this case, using TikZ should be fine. Maybe you can tell us a bit more about this diagram? Sep 19 at 17:12
• And this kind of drawing is pretty straightforward with basic TikZ commands that you may find useful to learn. Actually, TeX-SX is more of a help me with a specific issue I encounter rather than a do it for me entirely website. Sep 19 at 18:04
