Depends on what you want to make and on which level. Doing graphics for a desktop application will differ from doing it for a web application, for embedded devices or for a game. That being said for a beginner I would recommend starting with the examples in processing.org. This is basically a small IDE where you can make your code draw things in a window with minimal boilerplate (the boilerplate is hidden). There is a heap of examples, how to do easing functions, how to work with vectors, etc. The stuff learned there will be useful for anything where you need to work with a coordinate system.
