I wrote the C++ part of this codebase, would be happy to answer any questions about it here.

I see it's possible to embed it in jupyterlab, it seems to do a lot: * grid format * graph format * actual pivoting of data Is that right? It's using webassembly so in effect to do the pivot you must have created functions that exist in pandas? Has anyone ported pandas to webassembly? Is the grid editable? What are you using to create your output, html or canvas or something? I realise I could look this stuff up but…

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.

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

Briefly in the animation I see there's hierachical (or multi-dimensional) data used. Could you tell me about what sort of data (statistics, monitoring) this supports?

Also, what methods are available for getting data streamed [into Perspective]? I'm skimming through the docs, but am not quite getting it...
