We did it you guys! I managed to fully reproduce the plot that started this gnuplot wrapper journey many years ago.
We now have help and a library of functions to choose from.
You can find things you like and click on them to generate some pretty graphs really quickly.
We can now undo and redo!
You can now upload custom data files. 😁
And then reorder layers!
We can also do parametric and standard functional surface plots.
We now have a fancy function picker!
And night mode!
We now have mobile-friendliness.

(And currently quite visually unpolished but) We have a console at the bottom if you want to write raw gnuplot.

I will not lean too heavily on this as the whole point of this app is to be UI state to gnuplot script compiler.

Organising what is working into an example gallery.
@harish this is gnuplot?! wow.
@davidr Indeed.
@harish you mentioned mobile. is this viewable somewhere?
@davidr It is, it is a WIP webapp at https://gridpaper.org/

@harish this is amazing.
@davidr Why thank you. Enjoy it and open to all feedback.
@davidr I have updated the example set a great deal: https://gridpaper.org/examples

@harish I would never have guessed #gnuplot could compute a convex hull. Or that it could look this good. Why are the gnuplot default settings so incredibly awful if it can look this good?
@davidr This is the entire motivation for my project. To go through it, identify the key pieces and make it easy to use while looking good by default.
