Symplectic Geometry in 2D – Points, Lines, Circles

I've read a bit of this textbook on projective geometry: https://www.amazon.co.uk/Perspectives-Projective-Geometry-Th...

To some extent, the book justifies Arthur Cayley (the inventor of matrix algebra)'s adage that "Projective geometry is all geometry". Towards the end of the book, models of non-Euclidean geometries are built within CP^2. I've written up an overview in this Wikipedia sandbox: https://en.wikipedia.org/wiki/User:Svennik/sandbox

I've read 'Geometriekalküle': https://www.amazon.de/Geometriekalk%C3%BCle-Springer-Lehrbuc... from the same author ... thanks for your Wikipedia link.
