Description
viztracer is lovely. We want to be able to enable it when running the application, so we can test things.
https://viztracer.readthedocs.io/en/latest/
viztracer produces a json file on disk which can be converted into an html file which can be interactively viewed.
We want to be careful that we don't enable or import viztracer by accident when the flag is disabled. We should also look into remote hooking instead.
Please write a wiki entry with steps on how to use this argument & test a function.
