<h2>Graph Information</h2>
<!-- Do we actually allow mutiple graph_info, or is this just to access the nested data? -->
<p class="graph_info">This graph shows average waiting time/latency for different categories of disk operations. The times that include the queue times indicate how busy your system is. If the waiting time hits 1 second then your I/O system is 100% busy.</p>
