You can get rid of NaN by adding

"label": {
  "formatter": ""
}

to the first "series" object, e.g.

"series": [
  {
    "type": "bar3D",
    "shading": "lambert",
    "encode": {
      "x": "Year",
      "y": "Country",
      "z": "Life Expectancy",
      "tooltip": [0, 1, 2, 3, 4]
    },
    "label": {
      "formatter": ""
    }
  }
]
