graphviz - 如何将点图转换为 json 图？

Question

我想使用 sigma.js 来显示一些 DOT 图。但似乎 sigma.js 只支持 json 图形格式。

是否有一些 bash 工具或 javascript 模块可以将 DOT 图转换为 json 图？

例如从 DOT 图:

graph {
 n1 [Label = "n1"];
 n2 [Label = "n2"];
 n3 [Label = "n3"];
 n1 -- n2;
 n1 -- n3;
 n2 -- n2;
}

传输到 JSON 图:

{
  "nodes": [
    {
      "id": "n0",
      "label": "A node",
      "x": 0,
      "y": 0,
      "size": 3
    },
    {
      "id": "n1",
      "label": "Another node",
      "x": 3,
      "y": 1,
      "size": 2
    },
    {
      "id": "n2",
      "label": "And a last one",
      "x": 1,
      "y": 3,
      "size": 1
    }
  ],
  "edges": [
    {
      "id": "e0",
      "source": "n0",
      "target": "n1"
    },
    {
      "id": "e1",
      "source": "n1",
      "target": "n2"
    },
    {
      "id": "e2",
      "source": "n2",
      "target": "n0"
    }
  ]
}
