We currently are not a very educational UI, we should make more effort to make basics about flamegraph / profiles clear:

What is the profile type, how is it measured and what is covered?
Why is the memory usage different from the one shown in ps aux of the same service?
X axis is time in the timeline and resource usage in flame graph.
