Graphlib is my application that can create directional math graphs! It's free to use, open source, and has a precompiled static library (compiled with g++ (Debian 14.2.0-19) 14.2.0) if you don't want to compile it for yourself (SUPPORTED VERSIONS: Windows->x64, Linux->x86, x64)

You can contribute at any time via github issues!

If you like the project, give it a star! If you don't, tell me! I'll be reading the issues and can usually get back to you in 1-3 days!
