Provide overview of trace at a glance (one view)

e.g. Events over time histogram (stays at max zoom out, when range is selected other charts zoom) similar to LTTng scope.

As someone analyzing trace data, I need to see an overview of the trace data at a glance, so I can select a range that’s interesting, then filter, zoom, and get more details. As I zoom in this helps me maintain context.

Possible candidates:

• Events over time histogram?
• Statistics?
