I wonder if I could put select box in vega-lite graph using signals.
This is what I found for example.

The code of red area would be this.

  "signals": [
    {
      "name": "timeunit", "value": ["day"],
      "bind": {"input": "select", "options": [
        ["year"], ["month"], ["date"], ["day"], ["hours"]
      ]}
    },
    {
      "name": "measure", "value": "delay",
      "bind": {"input": "select", "options": ["count", "delay"]}
    },
