emacs-gl VS svg-lib

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.

You can hide/show icons, labels, create context menus with lisp callbacks for each menu item. The library uses svg-lib so you can use icons from various online collections supported by it. Under the hood it has tiny daemon, written in C that interacts with system tray via libappindicator. So, at least for now, the only supported OS is Linux.

Yes, he also uses svg to render a canvas and images. You can also check work by Rougier (/u/nicolas-rougier), he usually anounces his stuff in /r/emacs. He has done a lot with svg, check his svg-lib and svg-icons.

Isn't a "pile" just an "unorganized map"? Really, if you think of it: a pile of papers on a desk, could as well sitt in a folder. That should bring you back to normal desktop paradigm. Now implementing headings as "folders" shouldn't be overly difficult. You could implement a "pile" of headings as just subheadings to top headings and also render those top headings as either: svg icons, check for example svg-library by /u/Nicolas-Rougier, or you could use font-icons like in font-awesome or all-the-icons, to replace top-headings with an image or a font-icon. You would probably have to write your own minor-mode but it shouldn't be very difficult. You will probably need to use invisible-text property to hide headings and replace them with icons (that is normally how org and outline modes "fold" and "expand" content in headings), but that should not be very difficult.

the most basic UI changes you can do is by configuring faces (i recommend you take a look at the whole Controlling the Display section of the manual). going a bit beyond that, you can also take a look at the Widget Library as well for buttons, links, checkboxes and some other stuff. and there is also some packages and hacks by the community to display SVGs. see this reddit post and also some of Nicolas Rougier's work, more specifically his SVG lib.

You could, at least in theory, do lots of GUI stuff in Emacs itself already with SVG (org PNGs). See for example svg-lib by N. Rougier for doing stuff like buttons, toolbars and some other gui elements. You can do pop-up menus with child frames.

At the moment undetermined progress is what's supported out-of-the-box. Determined progress can be supported easily enough if svg-lib is used to create the progress bar.

Oh, I understood now what you mean. I think Emacs is definitely capable of doing this (https://github.com/rougier/svg-lib), but I don't think there's a plugin which has already done it :/.

i saw this repository and i want to use thoses icons in my org files, but i don't have much experience with emacs-lisp and neither org-mode (sorry for being a newbie). i tried to append (require 'svg-lib) and also i donwloaded the repository and before did it before requiring the module (i'm not sure if this is the right name)

Have you considered/tried doing something with svg-lib?

Can you open an issue on https://github.com/rougier/svg-lib (with screenshots)? I'm trying to fix the tag for any kind of font ant that would help.
