[edit] Summary

I made this myself using the graphics programming language TikZ, Beamer (LaTeX) and LaTeX

It displays how derivative values propagate according to the chain rule in automatic differentiation for the function

f (x 1, x 2) = x 1 x 2 + sin(x 1)

The only seed possible is $\bar{f} = 1$ which yields the complete gradient of $f (x 1, x 2)$ , $\partial f/\partial x_1 = x_2 + \cos(x_1)$ which comes out of the $x 1$ node, and $\partial f/\partial x_2 = x_1$ which comes out of the $x 2$ node.
