What kind of diagram is used to show the phase relationship between impedances at a given frequency?

A phasor diagram uses vectors, commonly called phasors, to graphically display the magnitude and phase relationships of alternating currents, voltages, or impedances. The length of the phasor represents the amplitude or magnitude, while its rotational angle relative to a reference axis represents the phase shift. The other options serve completely different purposes. Venn diagrams are used in set theory to show logical relationships, and near or far field diagrams describe the physical radiation patterns of antennas, not the electrical phase relationships of impedances.
