You might use FlameGraphs on its own, but users should consider one of its downstream packages:The flame graph displays the superposition of all stack traces that led to all memory allocations active at a given time (normally the time when the total amount of allocated memory was highest). A stack trace is represented as a column of boxes, where each box represents one function call in that call stack. The y-axis shows the stack depth.

This can be visualized as a flame graph, where the x-axis spans the total blocked time, and the flame graph shows the blocking code paths. As the entire profiler output is visualized at once, the end user can navigate intuitively to areas of interest. The shapes and locations in the flame graphs become visual maps for the execution of software.
