Probably I did not explain it properly: at the first stage this will be an expansion of GiNaC with the plotting functionality which provided in other CASes (like Mathematica or Maple) by the functions plot(...) and plot2(...). In other words, this will initially serves for plotting graphs of functions, and is not intended as a substation of the standard LaTeX output. Idea is that many symbolical expressions with one or two parameters may be better understood if plotted as a graphs of functions from these parameters. Expressions with a large numbers of parameters may be plotted if some extra parameters are substituted by appropriate numeric values. Since Asymptote is a powerful scripting language its applications in GiNaC is not necessarily limited to function plotting only. I can imagine that some GiNaC classes can be visualised as trees, graphs or diagrams and Asymptote can handle this as well. Best wishes, Vladimir -- Vladimir V.
