Display screen or portion thereof with transitional graphical user interface

Abstract

Description

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

FIG. 2 is the second image thereof;

FIG. 3 is the third image thereof;

FIG. 4 is the fourth image thereof; and,

FIG. 5 is the fifth image thereof.

The outer perimeter broken line depicting the display screen or portion thereof is for environmental purposes only and forms no part of the claimed design.

The remaining broken lines in the figures depict portions of the transitional graphical user interface which form no part of the claimed design.

The appearance of the transitional graphical user interface sequentially transitions between the images shown in FIGS. 1 through 5. The process or period in which one image transitions to another forms no part of the claimed design.
