I’m doing linear algebra with Owl. Owl-plplot works great for visualizing 2D vectors, but it doesn’t seem to capable of plotting 3D vectors.

I took a (quick) look at vanilla [Plplot](http://plplot.org/), [Oplot](https://github.com/sanette/oplot), and the [GNUplot bindings](https://github.com/c-cube/ocaml-gnuplot), but I didn’t find a simple way to plot 3D vectors.

I don’t need high quality plots, 3D surfaces, a lot of control or fancy features, just a coordinate system and some function to draw geometric primitives (points, lines, circles, etc.).

Did I miss anything or do I have to build this myself with the good old Graphics module?

Thank you!
