  Flamegraphs simply visualize this process by placing each of these recorded stacks side by side. The resulting visualization looks like "flames", hence a "flame graph". If you do this visualization where the "parent" of all the stack frames is on the top, rather than the bottom, you get a "waterfall graph", because it looks like a waterfall. It's the same thing though. Speedscope and DevTools visualize using the waterfall format, but I still call them flamegraphs anyway.
