I believe you'd need to port Python to WebAssembly to make much use of pandas - unaware of any projects attempting the former.

The grid is just a plugin for the excellent [Hypergrid](https://github.com/openfin/fin-hypergrid), which is editable, but you'd need to manually push those edits back to the engine for now.

WebAssembly code can talk to the rest of your JS (and therefore asm.js) code, right?

So PyPy.js runs Python in the browser via asm.js:

http://pypyjs.org/

https://github.com/pypyjs/pypyjs

Livebook uses PyPy.js to make a Jupyter-like notebook that runs entirely in the browser, and includes pandas:

And random plug for Observable in case you haven't seen it, a Jupyter-like Javascript environment, completely in the browser:

As historical background: Python was one of the early emscripten asm.js experiments: https://github.com/kripken/emscripten/tree/master/tests/pyth...

Nuitka can compile Python to LLVM IR, which can be compiled into WASM, I think.

which answers my other question, so it's canvas?

The frontend is actually pure JS/HTML - the WebAssembly part is just the data engine, and runs in a WebWorker for CPU isolation.

Hypergrid is a canvas-based renderer, yes.
