使用Vega Lite实现交替条纹的可视化效果，以下是示例代码：

{
  "data": {
    "values": [
      {"category": "A", "value": 25},
      {"category": "B", "value": 40},
      {"category": "C", "value": 30},
      {"category": "D", "value": 15}
    ]
  },
  "layer": [
    {
      "mark": {"type": "bar", "color": "white", "fillOpacity": 0.5},
      "encoding": {
        "y": {"field": "category", "type": "nominal", "axis": null},
        "x": {"field": "value", "type": "quantitative", "axis": null},
        "opacity": {"field": "index", "type": "nominal", "scale": {"range": [0,1]}, "legend": null},
        "tooltip": [{"field": "value", "type": "quantitative"}]
      }
    },
    {
      "mark": {"type": "bar", "color": "black", "fillOpacity": 0.5},
      "encoding": {
        "y": {"field": "category", "type": "nominal", "axis": null},
        "x": {"field": "value", "type": "quantitative", "axis": {"title": "Value"}},
        "opacity": {"value": 0, "legend": null}
      }
    }
  ]
}
