The remaining dashed broken lines illustrate portions of the graphical user interface and form no part of the claimed design. The dot-dash broken lines illustrate the boundary of the claimed design and form no part thereof.

The appearance of the graphical user interface sequentially transitions between the images shown in FIGS. 1 through 6 and FIGS. 7 through 12. The process or period in which one image transitions to another forms no part of the claimed design.
