所以我使用 d3 的库构建了一棵树,它可以通过动画折叠/展开。我对 d3 还是很陌生,我不确定如何将我的特定样式添加到战斗中。关于如何设置样式的任何建议<g>标签?

这是我想要的样子: enter image description here

这是它目前的样子: enter image description here

相关代码如下:

<!DOCTYPE html>
<meta charset="utf-8">
<style>
.node {
cursor: pointer;
}

.node circle {
fill: #fff;
stroke: steelblue;
stroke-width: 3px;
}

.node text {
font: 12px sans-serif;
}

.link {
fill: none;
stroke: #ccc;
stroke-width: 2px;
}
</style>

<body>
<script src="//code.jquery.com/jquery-1.11.3.min.js"></script>
<script src="//d3js.org/d3.v3.min.js"></script>
<script>
var margin = {
top: 20,
right: 120,
bottom: 20,

},

height = $(window).height() - margin.top - margin.bottom;

var i = 0,
duration = 750,
root;

var tree = d3.layout.tree()
.size([height, width])

var diagonal = d3.svg.diagonal()
.projection(function(d) {
return [d.y, d.x];

buildJson(function (data) {
