What is “gprof2dot” ?

GProf2Dot is a Python tool. It can be used to visualize such profiler output as a colorful directed call graph that makes it easy to understand the statistics. Profilers can be used to profile your code and dump the output to a file, as different profilers use different formats. The graph is produced in the DOT format, which can be viewed or converted to an image file.

Convert the output from many profilers into a Graphviz dot graph.!
