[NTG-context] Feynman Diagrams

Hi List, I’m looking for a way to include Feynman diagrams in my ConTeXt documents. I’ve used feynMF/feynMP and TikZ-feynman with LaTeX in the past, but it doesn’t look like either works directly with ConTeXt. My diagrams are pretty basic (example below). Does anyone have a ConTeXt solution they like? If not, I’ll add it to my list of summer MetaPost projects. Thanks! Gavin
