Found out about this at the #Moodle #STACKmath conference in #Durham. It is a set of pre-built items for creating STACK questions with #JSXGraph. Have not tried it yet, can anyone else commment?

Yesterday was day 1 of the 3 day International Meeting of the STACK community.
It was inspiring to be around so many smart people working on improving #maths education. There was good coverage of the use of JSXGraph for creating questions with graphics that students can interact with . Recent developments in Large Language Models and #AI have made it much easier to create the #Javascript code required for #JSXGraph .
#hyperbook v0.51.0 is out!
You can now add interactive geometry, function plots, charts & data visualizations with #jsxgraph

STACK ist echt der Hammer.

I just voted Vscode, though I am actually running a close relative vscodium

And at the moment I am using it for #jsxgraph for the #stack quesiton type running in #moodle... (possibly more than you wanted to know...)
There's a new release of #JSXGraph - https://jsxgraph.org/wp/2024-01-26-release-of-version-1.7.0/.
Among other things, it adds an 'implicit curve' object.
I thought I'd try it out in @numbas, then realised that the way Numbas evaluates expressions is far too slow for this kind of numerical approximation - it does a lot of dynamic type-checking that takes a long time.
So I nerdsniped myself into writing a routine to take a Numbas JME expression and make a function which is as close to native JS as I can get. It works on all of the operations that you'd expect a student to use, since those have plain-JS implementations. There's just the control flow stuff and things to do with collections that need the whole JME system.
And now that I've done that, I have a nice, real-time interactive function plotter!
I've made a demo question at https://numbas.mathcentre.ac.uk/question/152679/give-a-function-defining-an-implicit-curve/preview/
It's really simple to implement in Numbas: you set up a JSXGraph diagram, and fill in the function parameter of the implicit curve object with the expression the student typed. Just a few lines of code. Nice!
Earlier this week I was using #JSXGraph and wanted a slider to snap to 0 when it was close.
Yesterday I wrote the code to enable that, and this morning it was merged in!

In other news, the JSXGraph conference #JSXGraphConf2023 is next week: http://jsxgraph.org/conf2023/
I've just noticed that the #JSXGraph team are revamping their collection of examples: http://jsxgraph.org/share/. This is very welcome! The old wiki was very hard to use, and hard to tell if the example you wanted was there or not.
