This guide covers only the Racket language and libraries that are documented in The Racket Reference. The Racket distribution includes many additional libraries.
Racket provides many libraries for graphics and graphical user interfaces (GUIs):
The racket/draw library provides basic drawing tools, including drawing contexts such as bitmaps and PostScript files.
See The Racket Drawing Toolkit for more information.
The racket/gui library provides GUI widgets such as windows, buttons, checkboxes, and text fields. The library also includes a sophisticated and extensible text editor.
See The Racket Graphical Interface Toolkit for more information.
The pict library provides a more functional abstraction layer over racket/draw. This layer is especially useful for creating slide presentations with Slideshow, but it is also useful for creating images for Scribble documents or other drawing tasks. Pictures created with the pict library can be rendered to any drawing context.
See Slideshow: Figure and Presentation Tools for more information.
See 2htdp/image for more information.
See GL: 3-D Graphics for more information.
Web Applications in Racket describes the Racket web server, which supports servlets implemented in Racket.
The Racket Foreign Interface describes tools for using Racket to access libraries that are normally used by C programs.
Racket Documentation lists documentation for many other installed libraries. Run raco docs to find documentation for libraries that are installed on your system and specific to your user account.
PLaneT offers even more downloadable packages contributed by Racketeers.
