I don’t know much about quantum physics, but found Feynman Diagram to be a great example in data visualization when reading The Grand Design this morning –

• use visualization to explain obscure concept that’s not existing before
• it has all the necessary anatomy (but not excessive) to form a visualization  –
  • Time Series: initial state (at the bottom), final state (at the top);
  • Legends: solid line (Electron), wavy line (Photon), helix (Gluon)
  • States: arrows where it heads, and vertex where two meet
• The overall form of each diagram is simplified enough so it can be propagate quickly, considered that there could be indefinite possibilities in Quantum Theory
• The neat part is it comes with mathematics expression! For example, e⁺ e⁻ → 2γ
