<h2>About</h2>
This example simulates a real-time display of CPU utilization in a web farm.
Data is updated in real-time, and cells with changed data are highlighted.
You can also click "Find current server" to scroll the row displaying data for the current
server into view and flash it.
<h2>Demonstrates</h2>
<ul>
<li>setHighlightedCells()</li>
<li>flashCell()</li>
</ul>
<h2>Controls</h2>
<button onclick="simulateRealTimeUpdates()">Start simulation</button>
<button onclick="findCurrentServer()">Find current server</button>
