通过 CSS 和 javascript 绘制树和动态设计（架构）

Question

我尝试根据数据表用 CSS 和 javascript 绘制动态图。在此pdf中，您将找到我必须使用 css 和 javascript (html) 绘制的图表。
这是我想要做的一个示例（html和css）（但这个示例不是动态的）

/*Now the CSS*/
* {margin: 0; padding: 0;}

.tree ul {
	padding-top: 20px; position: relative;
	
	transition: all 0.5s;
	-webkit-transition: all 0.5s;
	-moz-transition: all 0.5s;
}

.tree li {
	float: left; text-align: center;
	list-style-type: none;
	position: relative;
	padding: 20px 5px 0 5px;
	
	transition: all 0.5s;
	-webkit-transition: all 0.5s;
	-moz-transition: all 0.5s;
}

/*We will use ::before and ::after to draw the connectors*/

.tree li::before, .tree li::after{
	content: '';
	position: absolute; top: 0; right: 50%;
	border-top: 1px solid #ccc;
	width: 50%; height: 20px;
}
.tree li::after{
	right: auto; left: 50%;
	border-left: 1px solid #ccc;
}

/*We need to remove left-right connectors from elements without 
any siblings*/
.tree li:only-child::after, .tree li:only-child::before {
	display: none;
}

/*Remove space from the top of single children*/
.tree li:only-child{ padding-top: 0;}

/*Remove left connector from first child and 
right connector from last child*/
.tree li:first-child::before, .tree li:last-child::after{
	border: 0 none;
}
/*Adding back the vertical connector to the last nodes*/
.tree li:last-child::before{
	border-right: 1px solid #ccc;
	border-radius: 0 5px 0 0;
	-webkit-border-radius: 0 5px 0 0;
	-moz-border-radius: 0 5px 0 0;
}
.tree li:first-child::after{
	border-radius: 5px 0 0 0;
	-webkit-border-radius: 5px 0 0 0;
	-moz-border-radius: 5px 0 0 0;
}

/*Time to add downward connectors from parents*/
.tree ul ul::before{
	content: '';
	position: absolute; top: 0; left: 50%;
	border-left: 1px solid #ccc;
	width: 0; height: 20px;
}

.tree li a{
	border: 1px solid #ccc;
	padding: 5px 10px;
	text-decoration: none;
	color: #666;
	font-family: arial, verdana, tahoma;
	font-size: 11px;
	display: inline-block;
	
	border-radius: 5px;
	-webkit-border-radius: 5px;
	-moz-border-radius: 5px;
	
	transition: all 0.5s;
	-webkit-transition: all 0.5s;
	-moz-transition: all 0.5s;
}

/*Time for some hover effects*/
/*We will apply the hover effect the the lineage of the element also*/
.tree li a:hover, .tree li a:hover+ul li a {
	background: #c8e4f8; color: #000; border: 1px solid #94a0b4;
}
/*Connector styles on hover*/
.tree li a:hover+ul li::after, 
.tree li a:hover+ul li::before, 
.tree li a:hover+ul::before, 
.tree li a:hover+ul ul::before{
	border-color:  #94a0b4;
}

   

<div class="tree">
    	<ul>

    			<a href="#">level_0</a>

我找到了解决我自己问题的方法，我不知道这是否是通用解决方案。

代码EJS

<div class="tree">
                            <ul>
                                <li>
                                    <a href="#">Niveau <%=level_selected%></a>
                                    <ul>
                                        <%var type_service = null;
                                            data.forEach(function(docService) {
                                            if(docService.type_service != type_service){%>
