Why is the reason that the flame graph in go pprof rotated 180 degrees?

The reason I can think of is that it seems that this conforms to the func calling order from top to bottom.

Thanks for anyone's discussion and replies

180 degrees in respect to what? ;)

I'd argue callgraphs have no "natural" orientation, top to bottom is as good as bottom to top or left to right (right to left feels off to me, but I read left to right, so I assume that's just a matter of familiarity)

Hey there,

In this issue, back then (https://github.com/google/pprof/issues/359), I linked my interpretation for the reasoning to switch from flame graph to "icicle graph". Just as you wrote, in some (many) cases, the investigations starts from the bottom of the graph, forcing a user to scroll down, when the graph was higher then their screen height.
