We introduce a new diagrammatic approach to perturbative quantum field theory, which we call flow-oriented perturbation theory (FOPT). Within it, Feynman graphs are replaced by strongly connected directed (digraphs). FOPT is coordinate space analogue of time-ordered and loop-tree duality, but it has the advantage having combinatorial canonical rules, combined with simplified $i\varepsilon$ depe...
