Graphics.jl is an abstraction layer for graphical operations in Julia. Its goal is to allow developers to write graphical programs in a manner independent of the particular graphical backend. One needs to load a backend package that implements the operations in its API; currently, Cairo.jl is the only such backend.

To get an organized overview of the API, try typing ?Graphics at the Julia REPL. You can see the same information in greater detail on the next page.
