lpviz is like Desmos, but for linear programming - I've implemented a few LP solvers in Typescript and hooked them up to a canvas so you can draw a feasible region, set an objective direction, and see how the algorithms work. And it all runs locally, in the browser!
If you go to https://lpviz.net/?demo it should show you a short tour of the features/how to use it.
It's by no means complete but I figured there may be some fellow optimization enthusiasts here who might be interested to take a look :) Super open to feedback, feature requests, comments!
For a 2-min intro to LP, I recommend https://www.youtube.com/watch?v=7ZjmPATPVzI
