Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Show HN: Vizzu – Open-source charting library focused on animating charts
5 projects | news.ycombinator.com | 17 Oct 2021
The best example of WASM being used to render to canvas (it's also visualizations) I've seen is "Perspective":
"Perspective is an interactive analytics and data visualization component, which is especially well-suited for large and/or streaming datasets. Originally developed at J.P. Morgan and open-sourced through the Fintech Open Source Foundation (FINOS), Perspective makes it simple to build user-configurable analytics entirely in the browser, or in concert with Python and/or Jupyterlab. Use it to create reports, dashboards, notebooks and applications, with static data or streaming updates via Apache Arrow."

Lots of great projects, one I used recently and a favourite was this:
Perspective 1.0.0, an open source BI tool built on WebAssembly
2 projects | reddit.com/r/programming | 15 Oct 2021
As far as customizing the Perspective datagrid, the story on this is evolving :) . With the 1.0 release, we've released an NFT demo with a more current version of the plugin API, as well as new plugin API docs. Replacing innerHTML is only costly if you trigger a relayout before the replacement, which you'd want to avoid - check the pudgy-penguins demo source for examples which replaces these with without the intermediate DOM tree being rendered (though this is brower-dependent). If you can't, e.g. the replacement is async or whatever, the underlying regular-table component has an API that allows you to return the DOM elements themselves per cell, but you'd need to write a simple plugin to integrate this as Perspective's version provides its own dataListener.2 projects | reddit.com/r/programming | 15 Oct 2021

Apache Arrow 3.0.0 Release

Not sure I follow, that page indicates that JS support is pretty good for all but the more obscure features (e.g. decimals) and doesn't mention data visualization at all? Anyhow, I've successfully used https://github.com/vega/vega-loader-arrow for in-browser plots before, and Observable has a fair few notebooks showing how to use the JS API (e.g. https://observablehq.com/@theneuralbit/introduction-to-apach...)
