- <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/>

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

- var dropdown = document.getElementById("layout");
- dropdown.onchange = function() {
- layoutMethod = dropdown.value;
- draw();
