Very interesting project. It seems to run a full blown TeX ... not LaTeX 
environment in the browser. 
In the background it needs about 13 MByte of WASM code + TeX configuration 
to + editor ... 

But it seems, that it still needs a backend to load assets like fonts ... 
As far as I can see, inspecting the live demo code. .. 

So there would be some considerable work to do, to slim the stuff down to 
make it usable with TW.

Thanks everyone for the answers,

I'm checking the links... I really liked the interactivity that the 
https://github.com/pyramation/LaTeX2JS plugin allows us to do. I've tried 
making a fast adaption here using a tiddler of type html but it doesn't 
work. I don't know why, if I save a file with the following content on my 
computer as html and open it with a browser it works:

I got it from the page https://latex2js.com/examples/index.html and just 
changed the relative paths to absolute paths... But well, inside TiddlyWiki 
it doesn't work as a type HTML, does anyone know why? Does the HTML type of 
tiddlers work exactly as an HTML file?

Hi,

I don't think there is any way to render a full latex document by 
javascript (or is there? https://github.com/kisonecat/web2js); you may have 
to actually run latex somehow, for example through php: 
https://github.com/scarfboy/phplatex There is a js library for rendering 
tikz that may be useful https://github.com/kisonecat/tikzjax

If making charts is more important than using latex, you can have a look at 
this 
short thread 
 about 
Charts.css  (although pie charts are not currently 
supported)

Best,
Anders

Hi, 
I think the short answer is no. :(
Katex supports a lot of LaTeX https://katex.org/docs/supported.html
But I don't think ticz drawings are supported. 
Im still kinda hoping https://github.com/pyramation/LaTeX2JS
takes goes viral and some mad genius makes a plugin out of it :) 
Maybe next it will week when I win the lotto! :)
I have used that with a free Dropbox hosting and Iframed it into a 
tiddlywiki. 
There are other diagramming plugins available for tiddlywiki. 
Have a search in the community vault:
