Equivalent embeddings of a graph
[Reposting comment as an answer, based on the OP's response to the comment.]

For a combinatorial definition, it seems like what you're looking for is a circular ordering around the vertices together with a map $f$ from the set of components to the set of faces such that $f(C_i)$ is the face of the graph that contains the component $C_i$. 

If you prefer a topological definition, I believe what you're looking for is that the map between the graphs can be extended to a map from the plane to itself that is isotopic to the identity. (Isotopy is, for example, the topological relation typically used to define two knots as being equivalent.)
