I decided to put together a similar, but probably a little more extensive scheme for the USSR.

Legend:
- yellow, "V-2 design",
- orange "design and construction improvement",
- dark yellow "using constructive and technical solutions",
- light green "kinship by developing team (same people on the team or same chief engineer)",
- blue "common construction elements" (passing into multiple rockets),
- purple "similar technical requirements and predecessor/similar designs study" - technically the weakest type of kinship, usually mere similarity.
Enjoy.
