I added the package and it downgraded Electron. I see on master it allows: 2, 3.0

Is there a point to 3.0? I'm not sure it's equivalent. 3.1 shouldn't be breaking, but that would disallow it?

And before up compatibility on DataStructures?

Might be bettor on a more recent master (and/or updated dependencies), but not too bad:

julia> @time using VegaLite
  2.167565 seconds (2.71 M allocations: 170.363 MiB, 2.00% gc time, 52.53% compilation time)

And pretty ok:
$ ./julia -O0 --compile=min --startup-file=no -q
