Display screen or portion thereof with transitional graphical user interface

Abstract

Description

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

FIG. 2 is a front view of the second image thereof;

FIG. 3 is a front view of the third image thereof; and,

FIG. 4 is a front view of the fourth image thereof.

The appearance of the transitional graphical user interface sequentially transitions between the images shown in FIGS. 1-4. The process or period in which one image transitions to another forms no part of the claimed design.

The outer perimeter illustrated by dashed broken lines in FIGS. 1-4 represents a display screen or portion thereof and forms no part of the claimed design. The contrast shown in grayscale in the figures represents a contrast of appearance. The remaining dashed broken lines shown in the drawings illustrate portions of the graphical user interface that form no part of the claimed design.

Claims

The ornamental design for a display screen or portion thereof with transitional graphical user interface, as shown and described.
