d3.js和弦的矩阵设计

Question

我找到了here一个d3.js和弦的例子。不幸的是，我不明白如何将他的matrix更改为我的数据。

var matrix = [
  [0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0], // Bob
  [0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0], // Giovanni
  [0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0], // Steve
  [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0], // Kevin
  [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0], // Art
  [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0], // Pyotr
  [0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0], // Rohan
  [0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0], // Rachel
  [1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], // Sasha
  [0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0], // Emily
  [0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0], // Lee
  [0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0], // Viva
  [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0]  // Poh
] 

我的数据以2个json文件分隔。第一个描述圆圈标签，颜色和尺寸

[
  {
    "color": "#996600", 
    "id": "chr03", 
    "len": 35020413, 
    "label": "chr03"
  }, 
  {
    "color": "#666600", 
    "id": "tig00007144", 
    "len": 40868, 
    "label": "tig00007144"
  }, 
  {
    "color": "#666600", 
    "id": "tig00026480", 
    "len": 95961, 
    "label": "tig00026480"
  },
...
]

另一方面，第二个文件描述了和弦图中每个标签之间的关系。

[
  {
    "source": {
      "start": 30824, 
      "end": 23113, 
      "id": "tig00007144"
    }, 
    "target": {
      "start": 33203431, 
      "end": 33211142, 
      "id": "chr03"
    }
  }, 
  {
    "source": {
      "start": 48387, 
      "end": 1, 
      "id": "tig00026480"
    }, 
    "target": {
      "start": 35010628, 
      "end": 34962190, 
      "id": "chr03"
    }
  }, 
...
]

如何将上述关系文件转换为适当的矩阵？

提前谢谢。
