Implement correct display of vector-like structs

[haakon-e]

Hi there,

I'm wondering if there's a "template" or suggested approach for how to make vector-like (or row-like) structs display "nicely" in Pluto.

This question was originally asked in rafaqz/DimensionalData.jl#725

Some key information from that post:

Printing DimArrays works nicely in (VSCode) terminal window:

but in Pluto, it only works for DimArrays with multiple dimensions:

The example above doesn't make clear why better printing is useful.

The package allows to construct arrays that with named dimensions. E.g.

julia> temperature = DimArray(round.(rand(5) .* 30, digits=1), (city = ["Vienna", "Berlin", "Prague", "Bratislava", "Budapest"],))
╭───────────────────────────────╮
│ 5-element DimArray{Float64,1} │
├───────────────────────────────┴──────────────────────────────────────── dims ┐
  ↓ city Categorical{String} ["Vienna", "Berlin", "Prague", "Bratislava", "Budapest"] Unordered
└──────────────────────────────────────────────────────────────────────────────┘
 "Vienna"      24.4
 "Berlin"       1.5
 "Prague"       3.0
 "Bratislava"  18.1
 "Budapest"    28.9

julia> temperature[city=At("Vienna")]
24.4

Would be nice if Pluto could display the correct labels, at least when the vector is unfolded

Thanks for the feedback!

Perhaps the Pluto tree viewer should be disabled for all DimArrays? @greimel What do you think?

If so, we can add an exception similar to Symbolics.jl here

Pluto.jl/src/runner/PlutoRunner/src/integrations.jl

Lines 43 to 48 in aaa835b

	Integration(
	id = Base.PkgId(UUID("0c5d862f-8b57-4792-8d23-62f2024744c7"), "Symbolics"),
	code = quote
	pluto_showable(::MIME"application/vnd.pluto.tree+object", ::Symbolics.Arr) = false
	end,
	),

(feel free to make a PR!)

@haakon-e Could you make a PR?
