Close to 100%, I only don’t call back the numbers my phone automatically labels as spam/fraud.

Graphs don’t have vectors, spaces do. A space is just an n-dimensional “graph”. Vectors written in columns next to each other are matrices. Matrices can describe transformation of space, and if the transformation is linear (straight lines stay straight) there will be some vectors that stay the same (unaffected by the transformation). These are called eigenvectors.
