过滤相关的节点和链接D3.js V5

Question

是否可以通过链接中的值过滤相关的链接和节点？

例如，过滤节点和链接的filter_columns = 12

 "links": [
    {
        "source": "13600",
        "target": "4112",
        "filter_column": 12
    },
    {
        "source": "4112",
        "target": "7423",
        "filter_column": 12
    },
    {
        "source": "7423",
        "target": "3042",
        "filter_column": 12
    },
    {
        "source": "3042",
        "target": "965",
        "filter_column": 12
    },
    {
        "source": "13600",
        "target": "965",
        "filter_column": 12
    },
    {
        "source": "11290",
        "target": "8953",
        "filter_column": 1
    },
    {
        "source": "8953",
        "target": "972",
        "filter_column": 1
    },
    {
        "source": "972",
        "target": "2376",
        "filter_column": 1
    },
    {
        "source": "11290",
        "target": "2376",
        "filter_column": 1
    }
],

您可以直接使用JS。假设您的数据位于data中-要过滤，请使用Array.filter。

var filteredData = data.filter(d => d.filter_column === 12)
