Jacobian transpose explainer

Jacobian transpose explainer is an interactive visualisation to help you understand multiplication by the Jacobian transpose. This is sometimes called "vector-Jacobian product" (vjp) as opposed to "Jacobian-vector product" (jvp). Reverse mode automatic differentiation performs multiplication by the Jacobian transpose.
