So someone else linked the original flamegraph site [0] and it describes icicle graphs as "inverting the y axis" but that's not only what's happening, right? You bucket top-down the stack opposed to bottom-up, correct?

It's certainly possible that what I encountered, labeled as an 'icicle graph', is a nonstandard usage of the term. But if so, that's a shame. I don't think inverting the y-axis is useful by itself, the different bucketing is what makes for an actually useful change.

Right, what is needed is something trie-like, with the root being the most fine-grained call.
