gprof2dot

gprof2dot is a Python script that converts the output from various profilers (e.g., cProfile, gprof, Valgrind callgrind, Linux perf, Java HPROF) into a Graphviz dot graph. This allows for visual analysis of performance bottlenecks and call flows within an application. The library is actively maintained with a current version of 2025.4.14, typically releasing updates on a yearly or bi-yearly basis.
