Display Screen or Portion Thereof with Graphical User Interface

FIG. 1 is a front view of the first image in a sequence for a display screen or portion thereof with graphical user interface, showing our new design; and,

FIG. 2 is the second image thereof.

The appearance of the transitional image sequentially transitions between the images shown in FIGS. 1 - 2 . The process or period in which one image transitions to another image forms no part of the claimed design.

The outermost broken line in the figures illustrates a portion of a display device that forms no part of the claimed design. The inner broken line next to the outermost broken line in the figures illustrates a portion of a display screen that forms no part of the claimed design. Similarly, the remaining broken lines represent features of the graphical user interface that form no part of the claimed design.
