Thanks! The are warning logs sent by StatsPlots, (Pluto recently started displaying logs). Can you also report this to StatsPlots.jl?

[aerdely]

Sure! Thanks.

The warning about violin moving to StatsPlots is being trigged here because this condition evaluates to false:
https://github.com/JuliaPlots/Plots.jl/blob/2896c5a25a40d72c635dd60b307fe1446ec70c2f/src/args.jl#L1578
That is, StatsPlots does not appear to be in the Main namespace when loaded in Pluto. @fonsp, is this expected behavior?

[fonsp]

Thanks for debugging! This is expected, we don't evaluate user code in Main because we manage the scope.

Plots should probably use Base.loaded_modules instead, e.g.

haskey(
	Base.loaded_modules, 
	Base.PkgId(
		Base.UUID("3fa0cd96-eef1-5676-8a61-b3b8758bbffb"), 
		"REPL"
	)
)

(You can get a reference to the package by using getindex instead of haskey.)

Can someone make a PR to Plots.jl to solve this? 💖

I found it's a duplicate of JuliaPlots/Plots.jl#3746, where a solution was previously started on but unfinished, so let's continue the discussion there.
