Your diagram attempts to show two sets labeled “born abroad to US citizen parent(s)” and “born in US to non-citizen parents”. These are disjoint sets yet you attempt to show an intersection.
You didn’t even separate the factors.
Incredible.
You're not reading it right, Ray.
The left circle is Jus Soli: Citizenship that comes from place of birth. The right circle is Jus Sanguinis: Citizenship that comes from parentage.
So the left part is people who get their citizenship solely from jus soli (born on US soil, but parents were not citizens at the time of birth, e.g., Marco Rubio). The center is people who have both jus soli and jus sanguinis (born on US soil of one or more citizen parents). And the right is those who get their citizenship solely from jus sanguinis (born a citizen abroad to one or more citizen parents, e.g., Ted Cruz.)
Maybe I can change it to make it more clear. I wasn't trying to produce something with total originality, I largely imitated the presentation of an existing but incorrect diagram.
