Once we have arrows in draw, it should be easy to plot direction fields.
It would be also possible to clic somewhere and get the curve, once the
interactive part is implemented. But I don't know how to get something
similar to the slide buttons in gnuplot, which is a very nice feature of
Jaime's plotdf.
In tcl-tk you have a lot of freedom you don't have in gnuplot, but in
gnuplot you have the advantage that there a lot of things already
programmed for immediate access.
Another example is 3d modelling. Gnuplot is very bad for this, but I
think that tcl-tk could make a good job here. I'm thinking in molecule
models moving around in 3d and things like that.
Just thinking aloud.
