As the number number and complexity of Feynman diagrams used in lattice QCD calculations grow, it becomes desirable to have automated tools for generating Feynman diagrams and converting said diagrams to code. Current tools for graph generation (FeynArts, QGRAF) are insufficient for these purposes, so we have created a new C++ program FeynGraphGen which replicates the functionality of QGRAF and provides a scriptable Python interface suitable for Lattice QCD code generation. In this talk I will give an overview of how FeynGraphGen and QGRAF work, why previous approaches fail for Lattice QCD, and the path forward towards applying FeynGraphGen to future lattice calculations.
