emacs-gl VS expenses

By the way, why only for pgtk? It would be nice to have it without pgtk or xwidgets (OpenGL was avaialable via xwidgets since quite some time, as a plugin).

If you need some 3D viz, there is also an Emacs binding to OpenGL. I believe it works only on X11, but I am not sure.

Webrender is using openGL. There are existing work out there regarding this. https://github.com/Jimx-/emacs-gl . But I would prefer WebGPU API over opengl's if I want to do computer graphics.

There is also a module to do OpenGL. You will have to compile the module yourself, but it shouldn't be too hard. No idea though how well, if at all, it works on macos.

Generally, librsvg (svg.el), is your best option to start with graphing in Emacs. Alternatively, if you are really ambitious you could take a look at Emacs-gl if you are familiar with OpenGL. Those are your drawing library. On top of them you will have to create some higher level library to draw charts, you could either adapt/convert one existing from some of other projects, for example there are several popular and good libraries for javascript that could probably work well with svg renderer. Perhaps take a look at some of Common Lisp charting libraries and see if you can make them work on top of svg.el or emacs-gl. For example, cl-2d seems quite reasonable to port to Emacs Lisp.

Many are suggesting using org-babel but that is exactly what I do not want. I want a library that could be used directly within an emacs-lisp code. This would make it easy to write Emacs packages that work with data. For example, in the package expenses that I wrote, I want to be able to plot and analyse expenses for different months/categories. Now, this could be done using some library from other languages but it would be much easier and nicer if there is a way to do this using emacs-lisp only.

As mentioned in another comment, if you are looking for something which is fully integrated in Emacs and not too complicated, checkout https://github.com/md-arif-shaikh/expenses.
