Javascript Question

draw a tree and dynamic design (schema) by CSS and javascript

i have tried to draw with CSS and javascript a dynamic graph according to a data table.
on this pdf you will find the graph which i have to draw it using css and javascript (html).

here is an example (html and css) of what i am trying to do (but this example is not dynamic)



/*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;
}

Answer

i found a solution for my own problem, i don't know if it's a general solution.

the code 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){%>
                                        <li>
                                            <a href="#"><%= docService.service%></a>
                                            <ul>
                                                <% var class_output = null;
                                                data.forEach(function(docOutput) {
                                                if(docOutput.type_service == docService.type_service){
                                                    if(docOutput.class_output != class_output){%>
                                                <li>
                                                    <a href="#"><%= docOutput.output%></a>
                                                    <ul>
                                                        <%
                                                        data.forEach(function(docInput) {
                                                        if(docInput.type_service == docService.type_service){
                                                        if((docInput.class_output == docOutput.class_output)&&(docInput.input != null)){ %>

                                                            <a href="#"><%=docInput.input%></a>
                                                        </li>
                                                        <%}}});%>
                                                    </ul>
                                                </li>
                                                <%}class_output=docOutput.class_output;

                                            </ul>
                                        </li>
                                        <% }type_service=docService.type_service;});%>
                                    </ul>
                                </li>
                            </ul>
                        </div>
