Feynman's diagrams (like the orbital model of the atom) were attempts to visualize a world we can't experience. Those of us who aren't deaf and blind begin to make audio-visual models of our macro world in childhood. We can agree with confidence that "that's a rock" (if not its physical properties). Even in our macro world, our models have limits. (What do radio waves 'look like' as they're emitted by different antennas? Go around buildings? We draw pictures.) But we're nearly deaf and blind to the quantum world. We have collections of indirect observations and math. Our models of it are necessarily limited by our inability to experience it directly. Those with math 'intuition' are in a better position ... but still.
