Plotting status in Octave

[Jordi Gutiérrez Hermoso]

I seem to have lost track of what's been happening with plotting in
Octave. I know Shai Ayal and Michael Goffioul were doing a lot of
work[1] towards moving away from gnuplot, and I remember some efforts
to move their merges from octave-graphics into main. What happened to
this?

And remember MathGL[2]? It looks very pretty. Is it going to be a part
of Octave?

I am *very* interested in getting high-quality 3d plots into Octave.
In fact, nowadays my primary use of Octave is for post-processing and
producing nice-looking plots. Octaviz has produced the best-looking 3d
plots for me so far, but it's abandoned upstream and I now agree with
Thomas Weber's opinion that combining VTK and Octave is too much work
and too resource-intensive. Compiling Octaviz requires compiling all
of VTK with some flex and bison arcana that I am unable to debug.

I'd appreciate a quick summary of what's been going with plotting in
Octave so I have an idea of where to start thinking of directing my
attention.
