<h2>Performance - World Cup Network</h2>
|
|
|
|
<div style="width:700px; font-size:14px;">
|
|
This example shows the performance of vis with a larger network. The edges in
|
|
particular (~9200) are very computationally intensive
|
|
to draw. Drag and hold the graph to see the performance difference if the
|
|
edges are hidden.
|
|
<br/><br/>
|
|
We use the following physics configuration: <br/>
|
|
<code>{barnesHut: {gravitationalConstant: -80000, springConstant: 0.001,
|
|
springLength: 200}}</code>
|
|
