Currently, the constructor of highdicom.ann.AnnotationGroup checks whether the coordinates passed via graphic_data are structured correctly. Specifically, it checks whether the first and last point of a POLYGON are identical (this is required by SR but not by ANN). However, it does not directly compare the floating point values for equivalence, but checks whether they are close. This can lead to an exception in case the coordinates are indeed very close to each other.
