It would make sense to solve the data download questions here as well, but if time is an issue, we can also postpone this.

Upgrading this for use in Maxwell is now more urgent than the data problem. I'd like to merge this as is

[rettigl]

I like the basic instructive rewrite, so general aproval. Some things, however, do not work for me, or could be improved, see comments.

Another thing to add would be the histogram normalization, maybe.

Absolutely!

Very thoroughly explained. I don't think a new user would have any issues getting into this workflow.

Deployment stopped because only main branch is allowed to deploy but I overrid it for checking. I think this is good to merge.

[rettigl]

Yes, it's clear that the deploy did not work. I downloaded the generated artefact and checked locally that it was fine.
However, before merging there are still several issues and todos to fix in the documentation.
@steinnymir @zain-sohail please feel free to finalize
