# Original Python:
# from math import pi
# from pyx import *
# 
# g = graph.graphxy(width=8)
# g.plot(graph.data.paramfunction("k", 0, 2*pi, "x, y = sin(2*k), cos(3*k)"))
# g.writeEPSfile("lissajous")
# g.writePDFfile("lissajous")
# g.writeSVGfile("lissajous")

using PyX

writeEPSfile(g, "lissajous")
writePDFfile(g, "lissajous")
