PyRGG is a user-friendly synthetic random graph generator that is written in Python and supports multiple graph file formats, such as DIMACS-Graph files.
It can generate graphs of various sizes and is specifically designed to create input files for a wide range of graph-based research applications, including testing,
benchmarking, and performance analysis of graph processing frameworks.
PyRGG is aimed at computer scientists who are studying graph algorithms and graph processing frameworks.
