[kwankyu]

Fixes #34822.

The template says that we are not yet accepting PRs. But I will just go ahead.

I cannot apply labels.

[dimpase]

I just added a label (but I have more rights).

You don't see a list when you click on the wheel, or you do see them, but can't added them?

[dimpase]

I'm really not sure why you can't do anything with labels - according to GitHub docs, it does not need more permissions than you already have: https://docs.github.com/en/issues/using-labels-and-milestones-to-track-work/managing-labels

[dimpase]

oops, sorry, you need a "triage access" to repo to apply labels:

What the hell is this Codecov comment? Spammer already?

I don't see the wheel.

This "Codecov Report" is extravagant. I wish that that is moved to the checks, somehow.

[github-actions]

Documentation preview for this PR is ready! 🎉
Built with commit: 952a6c9

[dimpase]

How can this be reviewed? Is this visible somewhere in the docs?

[kwankyu]

No. We should see interactive 3d graphics "before the branch" and "after the branch".

[kwankyu]

As the code is small, you may copy and paste the code directly into your local develop branch, and test the example
in the linked issue. No need to compile anything.

The example is

var('x,y,z')
implicit_plot3d((sqrt(x*x+y*y)-3)^2 + z*z - 1, (x,-4,4), (y,-4,4), (z,-1,1))

[dimpase]

lgtm. I tried the snippet provided, all good.

[kwankyu]

Thank you!
