title: pprof CPU Profile

[pprof](https://github.com/google/pprof), a profiling tool, can output callgraphs in Graphviz format.
This is a CPU profile of the `gzip` program, limited to the top 20 stack frames, generated from a `pprof.profile` with:
```
$ go tool pprof --nodecount=20 --dot pprof.profile
```
This illustrates how to create a legend in Graphviz.
Node sizes, arrow sizes, and increasing redness all indicate the number of samples in that callstack.
