Additionally, the profiler will generate a `callgrind.out` file that can be viewed with:

* [KCachegrind or QCachegrind](https://kcachegrind.github.io/)
* [Gprof2dot](https://github.com/jrfonseca/gprof2dot)
The gprof2dot tool generates [DOT](http://www.graphviz.org/doc/info/lang.html) files, which can be converted to images using the `dot` tool from [Graphviz](http://www.graphviz.org/) or viewed directly using [xdot](https://github.com/jrfonseca/xdot.py). The `-e` and `-n` parameters can be used to set the minimum percentage required to include a function in the output file. Observe these examples:
```bash
# Generating the .dot files:
gprof2dot -f pstats -e 0.05 -n 0.25 profile.1234567890123456.cprof -o profile.dot
gprof2dot -f callgrind -e 0.05 -n 0.25 callgrind.out.1234567890123456 -o callgrind.dot
# Converting to SVG and PNG formats:
dot callgrind.dot -Tsvg -o callgrind.svg
dot callgrind.dot -Tpng -o callgrind.png
# Alternatively, both commands in a single line:
gprof2dot -f pstats profile.1234567890123456.cprof | dot -Tsvg -o profile.svg
```
