I was referring to the table at https://github.com/zarr-developers/zarr-developers.github.io/blob/main/implementations/index.md - though I agree it would become out of date if done manually - perhaps a github actions workflow could be developed

A pre-v1 vs post-v1 could also work and be less prone to become out of date

This sounds great! I started an extremely rough pure R function for producing a single Zarr chunk from an R matrix here https://github.com/vitessce/vitessce-r/blob/keller-mark/zarr/R/zarr.R#L215 in case anyone is interested. Unfortunately I...

Just tested in [Shiny for Python](https://shiny.rstudio.com/blog/shiny-python-general-availability.html) and the counter example seems to work out of the box! https://github.com/keller-mark/anywidget-shiny-example/blob/main/app.py

This is a neat idea. You can get at least a preliminary basic solution working in user-land by implementing a subclass of AnyWidget: ```py import anywidget import traitlets class HtmlWidget(anywidget.AnyWidget):...

There are also https://github.com/thu-vis/Dynamic-Color and https://github.com/simonwarchol/psudo which could be explored (could be complementary to spaco)

The Zarrita.js ZipStore implementation could be helpful to reference https://github.com/manzt/zarrita.js/blob/main/packages/storage/src/zip.ts - R's built-in `unzip(list = TRUE)` might provide equivalent functionality to what the `unzipit` JS package is doing there https://stat.ethz.ch/R-manual/R-patched/library/utils/html/unzip.html
