The Feynman diagram is a visual representation of subatomic particles and their interactions. The diagrams are not meant to literally represent the particles and their interactions but rather a way to represent the mathematical formulas that describe them. They are extremely useful in quantum field theory and other areas of physics – Frank Wilczek, who won the 2004 Nobel Prize in Physics, credits Feynman diagrams as an invaluable tool in his research.
