An easy and fun plotting API for pygfx.

Pygfx is pretty powerful and flexible, but it's API is somewhat verbose for doing explorative visualization. This is intentional, because designing a (high-level) API comes with many subtle choices.

In visvis2 we provide a minimal API to setup a pygfx visualization. Other libs may do the same, but with different API's. Like e.g. fastplotlib!

The idea of visvis2 is to be a thin API layer over pygfx. It's so thin you can still see pygfx. It provides an easy API to create subplots (we call them "views"), and position them. It has methods to add content to the scene. These methods auto-convert input data (e.g. convert lists to numpy arrays) for convenience. But they simply return pygfx objects.

No dependencies except pygfx itself.

For now this lib does not create its own world object classes or shaders. I.e. all is vanilla pygfx.

Very much experimental. Was triggerd by my old prof asking for viz tools for medical visualization. Not sure if I'll push this much further. Fastplotlib may be equally suited with some added suppoer for e.g. volumes.

For now it's a nice toy to get a feel for what's needed from pygfx to make a lib like this work. E.g. axes, grids, ticks, legends ...

And it can serve as an example for others how have plans for creating a library on top of pygfx.

Visvis is a Python visualization library that I started during my PhD. It actually still works, but is sub-optimal in many ways. After various detours it feels like with pygfx I'm finishing what I started with visvis. This lib (visvis2) brings it full circle by providing the easy API too.

Visvis2 is not compatible with visvis in any way.
