>In our case we output the profile buffer to a file and read that into the visualization tool which is conveniently built into Chrome. (You can find more information about the tracing tool here and you can try it out by typing “chrome://tracing/” into your Chrome browser. It is designed for web page profiling, but the format of the input profile data is a simple json format that can be easily constructed from your own data.)

Clever! Never heard of doing that but it makes sense.

Another term for these profiling charts in Chrome is flame charts, you might be able to find even more tools by it.

Yup, basically Chrome is using an inverted flame graph (See [1] for additional infos and tools).
