<h1>Regions</h1>

Below is a table containing a summary of all the user-defined regions in the trace.
Regions are grouped by the region type and the point at which the region started.
The rightmost column of the table contains a latency histogram for each region group.
Note that this histogram only counts regions that began and ended within the traced
period.
