## Graphics: Legacy Library🔗ℹ

(require graphics/graphics) | package: htdp-lib

The viewport graphics library is a relatively simple toolbox of graphics commands. The library is not very powerful; it is intended as a simplified alternative to racket/gui’s full graphical toolbox.

The graphics library originated as SIXlib, a library of X Windows commands available within Chez Scheme at Rice University. The functionality of that library has been reproduced (with backward compatibility) in this version.
