How to make pluto work with vegalite interactivity?

[canelhasmateus]

Is there any way to make Pluto work with Interactive Vega Scripts? It seems to currently embed a static image.

I'm talking about configs such as the one below:

{
  "config": {"view": {"continuousWidth": 400, "continuousHeight": 300}},
  "data": {
    "url": "https://cdn.jsdelivr.net/npm/[email protected]/data/cars.json"
  },
  "mark": "point",
  "encoding": {
    "color": {
      "condition": {
        "type": "nominal",
        "field": "Origin",
        "selection": "selector064"
      },
      "value": "lightgray"
    },
    "x": {"type": "quantitative", "field": "Miles_per_Gallon"},
    "y": {"type": "quantitative", "field": "Horsepower"}
  },
  "selection": {"selector064": {"type": "interval"}},
  "$schema": "https://vega.github.io/schema/vega-lite/v4.8.1.json"
}

You can generate the VLSpec in your notebook and get it in interactive form using ElectronDisplay. Here's your example (plus a title that can be set interactively in the notebook) done two slightly different ways:

In the first approach, I made a VLSpec using your exact JSON string, linked the TITLE (text box) variable to it with @set, and sent it to a separate window, where the plot highlighting works exactly as expected.

In the second approach, I avoided the additional Setfield dependency by reformatting the JSON into VegaLite.jl's DSL. I'm not sure which one I like better; they produce identical outputs.
