          Args:
              structures (Structure): List of structures
              two_theta_range ([float of length 2]): Tuple for range of
                  two_thetas to calculate in degrees. Defaults to (0, 90). Set to
                  None if you want all diffracted beams within the limiting
                  sphere of radius 2 / wavelength.
              annotate_peaks (bool): Whether to annotate the peaks with plane
                  information.
              fontsize: (int) fontsize for peak labels.
