因此，我已经构建了一个使用d3库将动画合拢/展开的树。我对d3仍然很陌生，我不确定如何将我的特定风格加入到战斗中。任何建议如何样式<g>标签？d3树<g>标记填充/边框整体造型
这是我希望它看起来像： 
而且这里是它目前的样子： 
下面是相关代码：

你的数据是什么样的？所以我可以创建一个小提琴.. – thatOneGuy
这里是一些可以工作的json的要点https://gist.github.com/Quixomatic/4cc96a44bca4fb81ce963ceaada89569 –
您正在使用两组数据：类别，json和technologies.json .. – thatOneGuy
