圓包節點x，y和r未定義d3.v4

Question

當我查看節點時，x和y未在我的數組中定義。我的代碼最初是在版本3

var tree = d3.nest().key(node => node.parent) 
.rollup(function (leaves) {return leaves.length; }) 
.entries(data); 

var treeRoot = { 
    key: "root", 
    value: "100", 
    values: tree 
}; 


    var pack = d3.layout.pack() 
    .size([width, height - 50]) 
    .children(function(d) { return d.values; }) 
    .value(function(d) { return d.values; }) 
    .padding(10); 

var nodes = pack.nodes(treeRoot); 

initial work no chart yet

刪除了彙總。將值更改爲此;

.value(function(d) { return d.value; })
