Javascript Highcharts:网络图：标记半径=连接数

在highcharts网络图中： ，我看不到动态调整标记半径以匹配标记的连接数的方法

例如：

data: [
    ['Jim', 'Michael'],
    ['Jim', 'Pam'],
    ['Jim', 'Dwight'],
    ['Michael', 'Pam'],
]

我们希望看到：

• 吉姆的标记半径为3
• Michael的标记半径为2
• Pam的标记半径为2
• 德怀特的标记半径为1

您需要通过迭代数据链接并计算每个节点的连接数来计算半径

Highcharts.addEvent(
    Highcharts.Series,
    'afterSetOptions',
    function (e) {
            
            let nodeCounts = {};
      
            //count connections for each From or To node
            e.options.data.forEach(function (link) {
                nodeCounts[link[0]] = (nodeCounts[link[0]] || 0) + 1;
                nodeCounts[link[1]] = (nodeCounts[link[1]] || 0) + 1;
            });

            let radiusFactor = 3; //radius multiplier to graphically enlarge nodes

            //map each nodeCount to a node object setting the radius
            e.options.nodes = Object.keys(nodeCounts).map(function (id) {                   
                return {
                id: id,
                marker: {   radius: nodeCounts[id] * radiusFactor }
                };
            });
        }    
);
