<h2>Hierarchical Layout - User-defined</h2>
|
|
<div style="width:700px; font-size:14px; text-align: justify;">
|
|
This example shows a the effect of the different hierarchical layout methods. Hubsize is based on the amount of edges connected to a node.
|
|
The node with the most connections (the largest hub) is drawn at the top of the tree. The direction method is based on the direction of the edges.
|
|
Try switching between the methods with the dropdown box below.
|
|
</div>
|
|
Layout method:
|
|
<select id="layout">
|
|
<option value="hubsize">hubsize</option>
|
|
<option value="direction">direction</option>
|
|
</select><br/>
|
|
<br />

<div id="mynetwork"></div>

<script language="JavaScript">
|
|
var dropdown = document.getElementById("layout");
|
|
dropdown.onchange = function() {
|

layoutMethod = dropdown.value;
|

draw();
