+graphs to the representation of complex 3D scenes.  GR is essentially based on
+an implementation of a @acronym{GKS, Graphical Kernel System}.  As a
+self-contained system it can quickly and easily be integrated into existing
+applications (i.e. using the @code{ctypes} mechanism in Python or @code{ccall}
+in Julia).")
