@CreativeSelf0 thanks. Can you please let me know how did you create this chart? I would like to do some changes in there before we merge it to the docs?

@deshraj I mostly use excalidarw, it's pretty decent tool. I love it.

thanks for your contribution @CreativeSelf0 . This is a great one. But we will have to close this one, as the architecture has changed a lot. We plan to publish a new one in the future.
