Symbols of multiple polylogs have recently become important in calculations of amplitudes in N=4 SYM. In this talk, I give a simple pictoral presentation of multiple polylogs and their symbols. I also discuss the Hopf algebraic structure underlying the multiple polylogs, and give some new relationships between different multiple polylogs based on the symmetries of my pictoral presentation that are exact on the symbol level, but complicated on the level of the actual multiple polylogs..
