The outermost broken line illustrates a display screen or portion thereof and forms no part of the claimed design. Stippling in the drawings is used to indicate a contrast in appearance, with no specific color or other feature being claimed. The remaining broken lines represent elements of the display screen or portion thereof with a transitional graphical user interface that form no part of the claimed design. The appearance of the transitional image sequentially transitions between the images shown in FIGS. 1 - 3 in the first embodiment, FIGS. 4 - 6 in the second embodiment, FIGS. 7 - 9 in the third embodiment, FIGS. 10 - 12 in the fourth embodiment, FIGS. 13 - 15 in the fifth embodiment, FIGS. 16 - 18 in the sixth embodiment, FIGS. 19 - 21 in the seventh embodiment, FIGS. 22 - 23 in the eighth embodiment, FIGS. 24 - 25 in the ninth embodiment, FIGS. 26 - 27 in the tenth embodiment, FIGS. 28 - 29 in the eleventh embodiment, FIGS. 30 - 31 in the twelfth embodiment, FIGS. 32 - 33 in the thirteenth embodiment, and FIGS. 34 - 35 in the fourteenth embodiment. The process or period in which one image transitions to another image forms no part of the claimed design.
