VEGA Json url 从 Github 加载失败

Question

我无法将 json 文件从 github 存储库加载到 VEGA 在线编辑器。下面的 VEGA 数据数组：

    "data": [
    {
      "name": "tree",
      "url": "https://github.com/omerakko/VEGA/blob/288ea5a5cc2a2e118eec6301f1b20288cffbef5b/vegaTreemapData.json",
      "format": {"type": "json", "parse": "auto"},
      "transform": [
        {"type": "stratify", "key": "id", "parentKey": "parent"},
        {
          "type": "treemap",
          "field": "percentage",
          "sort": {"field": "value"},
          "round": true,
          "method": {"signal": "layout"},
          "ratio": {"signal": "aspectRatio"},
          "size": [{"signal": "width"}, {"signal": "height"}]
        }
      ]
    },
    {"name": "testData", "source": "tree"},
    {
      "name": "nodes",
      "source": "tree",
      "transform": [{"type": "filter", "expr": "datum.children"}]
    },
    {
      "name": "leaves",
      "source": "tree",
      "transform": [{"type": "filter", "expr": "!datum.children"}]
    }
  ],

github 目录设置为 public.

我收到一条[警告] 加载失败的消息。我是否缺少配置？

编辑：答案是关于正确使用 github。 "url": "https://github.com/omerakko/VEGA/blob/288ea5a5cc2a2e118eec6301f1b20288cffbef5b/vegaTreemapData.json" 指向 html 页面，而不是 json 文件。

解决方案：通过单击 github 中文件可用的“原始”按钮来替换“url”link，以访问未预处理的数据
