I presume that you are just using "group" to mean "set"- there are other mathematical meanings but "set" seems best to fit what you are talking about here. By "graph" I think you are referring to a graph in an xy-coordinate system, basically, a curve in two dimensions. But are you referring specifically to continuous curves? Piece-wise continuous curves? By "equation" I think you are referring to a relation between x and y such as y= 2x or x^2+ y^2= 4. But, since you are asking about comparing the size these sets would you regard 2y= 4x different from y= 2x? Since those are satisfied by exactly the same (x, y) pairs, they correspond to the same graph.
