I know that the genus of a surface is the number of holes. Thus it is easy to "see" just by looking at the surface. I also know that algebraic curves have a genus as well, that appear in the Riemann-Roch theorem. I would like to know if there is also a geometric / visual interpretation of it.

How does one see the genus of a curve?
