CLAIM The ornamental design for a transitional graphic user interface for a display screen, as shown and described.
Description:
FIG. 1 is a front view of the first image of a transitional graphic user interface for a display screen showing my new design;
FIG. 2 is a front view of the second image thereof; and,
FIG. 3 is a front view of the third image thereof.
The appearance of the graphic user interface sequentially transitions between the images shown in FIGS. 1 3. The process or period in which the image transitions to another forms no part of the claimed design. The broken line showing of a display screen and the text is for illustrative purposes only and forms no part of the claimed design.
