Title: Graphical Functions

Abstract: Graphical functions are special QFT-amplitudes for massless particles in position space.  We explain that there exist powerful tools to calculate graphical functions and illustrate how to use graphical functions to obtain high loop order results in QFT-renormalization with dimensional regularization.
