Example 7.4 - Plotting implicit equations

In this example we will plot curve given by implicit equation:

   export(plot,implicit):
      Arabesque:=implicit(
      x*sin(x)+y*sin(y), x=-20..20, y=-20..20,
      Grid=15,
      Colors=[RGB::Black]
   ):
    

   plot(
      Arabesque,
      Scaling=Constrained,
      BackGround=[0.8,0.8,1],
      LineWidth=5
   )
