Sunburst不完整分段

Question

我一直在努力理解d3 v5 sunburst中使用的arc函数，但我无法完全理解它。我可以绘制sunburst，但一旦它超过深度1，弧就不完整了。它们的规模似乎大约是正在进行的部分的一半。有人能解释一下我在这里丢失的那块吗？

let data = {
"name": "DEMO",
"children": [{
"Build": "1",
"value": "90",
"children": [{
"Build": "1",
"value": "70",
"children": [{
"Build": "1",
"value": "60",
}]
}]
},
{
"Build": "2",
"value": "95",
"children": [{
"Build": "2",
"value": "85",
"children": [{
"Build": "2",
"value": "65",
}]
}]
}
]
}
function createSunBurst(data) {
let container = document.getElementById("container")
let width = 200
let height = 200
let radius = (Math.min(width, height) / 2) - 5
let format = d3.format(",d")
let partition = data => d3.partition()
.size([2 * Math.PI, radius])(d3.hierarchy(data)
.sum(d => d.value)
.sort((a, b) => b.value - a.value))
let root = partition(data)
d3.select("#container")
.append("svg")
let svg = d3.select("svg")
.style("width", "100%")
.style("height", "100%")
.attr("id", "canvas")
.append("g")
.attr("class", "center-group")
let arc = d3.arc()
.startAngle(d => d.x0)
.endAngle(d => d.x1)
.innerRadius(d => d.y0)
.outerRadius(d => d.y1 - 0)
svg.selectAll("path")
.data(root.descendants().filter(d => d.depth))
.enter()
.append("path")
.attr("stroke", "white")
.attr("fill", "green")
.style("fill-rule", "evenodd")
.attr("d", arc)
}
createSunBurst(data)

#container {
height: 100vh;
}
.center-group {
transform: scale(1, 1) translate(50%, 50%);
}

自从发布这篇文章以来，我一直在继续研究。我已经解决了我的问题。弧线不是问题所在。相反，问题在于我最初计算分区数据总和的方式。

看完这个答案后，我解决了我的问题。
