In this paper an extended SABR model is presented. Is there any place where the model is implemented in R or Python? I want to generate the graphs without going through a long coding process.

If you have it implemented yourself and is willing to share, please let me know.

Part of the fun is actually programming it yourself. Anyways,

The book on Financial Modelling by Joerg Kienitz and Daniel Wetterau has Matlab code for SABR. You might be able to adapt/extend it for ZABR.
