As someone else already mentioned in the comments, graduated symbols are only available for point features, not polygons. So first you should create a points layer by using the "Centroids" geoprocess.

Thanks so much, I am trying to overlay state level excel data on my country shape file. I can't get the size option though. Only the color option. Could you please help?

I don’t have the method selection in my symbology, you have any idea what else I can do to change the method? I have QGIS Version 3.30.2, anyone else has any idea what to do?
